CADAM Drafting Changes in V4R1.7


FK Analysis Change

You can now measure the approximate distance between two indicated points (to measure non-geometric elements such as raster images, for example). Select menu option /PT- ELEM/, and indicate a location for the start and end points. A rubberband guideline is displayed after you indicate the first point, and you can press YN to back up and redefine either point.

 

FK Aux View Change

Because of new options in the CADAM Drafting profile utility (cadprof), you might see a change in the way that balloons and text elements (arrow text, balloon text, notes, dimension text and textlines) behave in scaled views. The options, set by your CADAM Drafting system administrator, produce the following results:

 

Option

Result

Scale balloon radius?

When set to Yes, balloons are scaled when a view is scaled.

When set to No, balloons are not scaled when a view is scaled.

Scale all text?

When set to Yes, text is scaled when a view is scaled.

When set to No, text is not scaled when a view is scaled.

When the option for text elements is turned on (Scale all text? Yes), notes are scaled even if you set the /SCALE-TURN/ option to /NO SCL/ in function key NOTE. See your system administrator for information about the cadprof settings at your site.

No is the default and is the behavior of previous releases of CADAM Drafting and Professional CADAM.

 

FK Circle Change

A circle can be created by selecting a circle (it’s center point is used), a point, a key-in radius and an indicate to identify the region the circle will lie in. 

 

FK Detail Change

Because of new options in cadprof, you might see a change in the way balloons and text elements in dittos behave. The options, set by your CADAM Drafting system administrator, produce the following results:

 

Option

Result

Scale balloon radius?

When set to Yes, balloons in dittos are scaled when hung in a scaled view.

When set to No, balloons in dittos are not scaled when hung in a scaled view.

Scale all text?

When set to Yes, text in dittos is scaled when hung in a scaled view.

When set to No, text in dittos is not scaled when hung in a scaled view.

When the option for text elements is turned on (Scale all text? Yes), notes are scaled even if you set the /SCALE-TURN/ option to /NO SCL/ in function key NOTE. See your system administrator for information about the cadprof settings at your site.

No is the default and is the behavior of previous releases of CADAM Drafting and Professional CADAM.

 

FK Dimension Change

The following new options have been added to the main menu:

/GLOBAL/ Allows you to quickly change the specifications (standard, geometric parameters, and text string format settings on the SPEC panel), of associative dimensions.

You can group the associative dimensions in a drawing to change them all in a single step, or you can select only the associative dimensions you want to change.

/TOUCH/ Allows you to quickly create the following dimensions, using the same technology available in function key VDS:

 

FK Draft Change

Ability to align views in a draft sheet or layout

When you edit a defined sheet or layout, you can now align one view with respect to another view in the same sheet or layout. To access the new menu option /ALIGN/, press function key DRAFT, select menu option /EDIT/, and select a sheet or layout from the list.

Suboptions under /ALIGN/ do the following:

/AXIS X/ Moves the second view horizontally until its origin is aligned with the origin of the reference view.

/LEFT/ Aligns the two views along the left sides of the clip boxes.

/RIGHT/ Aligns the two views along the right sides of the clip boxes.

/AXIS Y/ Moves the second view vertically until its origin is aligned with the origin of the reference view.

/TOP/ Aligns the two views along the top sides of the clip boxes.

/BOTTOM/ Aligns the two views along the bottom sides of the clip boxes.

Externalize Draft Data

Provides IUE read/write of the draft (plotting sheets) data.

 

FK Files Changes

External File Translator (EFT) - Option for Layers-to-Overlay Translation

When you import DXF and DWG files, you can either:

To enable the new layers-to-overlay mapping, set the IMAP_LAYER parameter to OVERLAY on the EFT Input Parameters panel.

Mapping each layer to a separate CADAM Drafting model allows you to show or no-show specific models.

External File Translator (EFT) - Support for DWG R13

Provides R13 support for input of DWG files.

External File Translator (EFT) - NT

With PTF 1, EFT does not require a group/user concept and works with fully qualified path names. Therefore, all child members of an overlay model are required to be present in the same directory as the parent model for output translation.

Wildcard IDs

The method of using wildcards to display a subset of a list of drawings has changed. You can now use an asterisk (*) to denote a series of characters and a question mark (?) to denote a single character. Commas are not valid characters in a search string.

For example, this wildcard: dra* or draft?test

would return both of the following sample drawing IDs:

draft test

draft_test

while this wildcard: draft_?est

would return only this sample drawing ID:

draft_test

Note that the search criteria is case sensitive.

File-naming conventions

File-naming conventions in CADAM Drafting have been changed to provide consistency across platforms.

Call lists will now recognize and display both "D_" (UNIX) and ".cdd" (Windows NT) files - you can call both types of files.

All file types are filed with the ".cdd" extension. If a "D_" file is called and refiled, it will automatically have the ".cdd" extension applied and "D_" prefix will be deleted.

Temp Plot Data on NT

Temporary plot data is available on CADAM Drafting-NT.

 

FK Group Changes

Hidden-Line Removal

Menu option /HLR/ (hidden-line removal) has been added to the main menu to enable you to control the display of lines for overlapping geometry. This feature allows you to group the elements that form a layer in a drawing, assign the group a priority, and define the display style for lines that lie beneath it. Geometry with a higher priority obscures geometry with a lower priority.

The style that you assign to a group determines whether or not underlying, lower priority geometry is displayed. The style options are HIDDEN and DASHED, as shown above.

/ABORT/ Suboption for Translations

When you select menu option /TRANSL/, a new suboption /ABORT/ is available on the menu line. Unlike the /ABORT/ option on the main menu line, /TRANSL/ /ABORT/ allows you to undo a translation operation (/MOVE/, /TURN/, or /SCALE/), without disbanding the group.

Edit Feature

The VIEW option has been added to the Edit feature. This option enables you to view the content of the clipboard (the last selection to be cut or copied) and to define a pivot point for it. This option is available when you select the EDIT command bar button.

 

FK Line Changes

Line Displayed When Drawing With /PT-PT/ Option

A rubber-band line is now displayed when you use /PT-PT/ to create a point-to-point line. After you define the first point of the line, the rubber-band line is displayed between that point and the cursor so that you can see the line as you draw it.

Shortcuts for Creating Polygons, Boxes, and Centerlines

You can quickly create polygons, boxes, and centerlines with three new options on the main menu:

/POLY/ Allows you to create a polygon in as few as three steps:

    1. Define a circle.

You can either selecting an existing circle or define a temporary circle.

    1. Define the size of the polygon.

Indicate inside the circle if you want the polygon to fit inside the circle (so that the points of the polygon intersect the circle).

Indicate outside the circle if you want the polygon to fit outside the circle (so that the lines of the polygon intersect the circle).

  1. Specify the number of sides.
  2. You can specify from 3 to 32 sides.

    Sub-options /FLAT/ and /ANGLE/ allow you to control at what angle the polygon is displayed, as shown below.

/BOX/ Allows you to create a square or rectangle by defining opposite corner points.

If you indicate or select a point, a rubberband box is displayed to show the shape of the box as you move the cursor. After you define the second point, the box is displayed, comprised of four lines and four points. You can optionally erase the box by pressing Yes/No.

Boxes are created parallel to the window regardless of how the window or view is turned.

/CNTR/ Allows you to create crossed centerlines for circles, arcs, and ellipses. Simply select the element, and two perpendicular lines are displayed at the center of the shape.

On a circle, the lines are placed at zero degrees and 90 degrees. On an ellipse, the lines are placed at the angle of the ellipse. The centerlines extend past the edge of the circle or ellipse by half the radius, and you can optionally lengthen or shorten them by indicating. To turn the centerlines, key in an angle. You can optionally erase the centerlines by pressing Yes/No.

 

Additional Constraint Created in /PT-PT/ Option

When the OUTSIDE VDS option is active, using the /PT-PT/ option to create a line to or from a circle or ellipse causes a relimit constraint to be made (in addition to a tangent constraint, as in previous releases).

To set the OUTSIDE VDS option, select function key VDS, menu options /GEOM CSTS/ and /AUTO CSTS/, and select the CST LIST button on the command bar.

 

FK Note Changes

Text-Find

Menu option /TEXT FIND/ has been added to the main menu to provide the following capabilities:

You can search for a find string that occurs in any note, dimension text, or text line. You can also search for a text string that is attributed to an element.

When you perform a search, the system highlights the first occurrence of the find string and centers it in the window.

You can change a find string that occurs in any note, dimension text, or text line.

/CHNG/, /TURN-SCALE/, /SHOW/

The TURN/NO TURN or SCALE/NO SCALE parameters of a note can be queried through /CHNG/, /TURN-SCALE/, /SHOW/.

Edit Dimension text with NOTE

Dimension text can be edited in FK NOTE / NOTE / and / CHNG / / EDIT /.

 

 

FK Offset Change

A ditto or symbol (dot, rivet, triangle, or special) can now be selected to define an offset distance. Host CADAM compatibility.

 

FK Show Change

Selecting menu option /ERASE PTS/ and pressing YN to erase points in a drawing will not erase points with geometric constraints.

 

FK Symbol Changes

Line Weights

Additional line weights are available for the following symbols. These options are set in cadprof (default values are in italics):

Arrowheads light, medium, or heavy

Balloons light or medium

Deltas light or medium

See your system administrator for information about cadprof settings at your site.

Alignment Options for Text in Balloons

When you create text in balloons, you now have three choices for text alignment: /LEFT/, /CENTER/, and /RIGHT/. You must select the option you want to use before you create the balloon.

Options for Arrow Standards

You can now choose a standard for an arrow before you create it. The new option is displayed on the menu line when you select /ARROW/, and you can select it to toggle between /JIS/ and /ANSI/.

/FONTS/ - Modifying a Font String

You can modify the fill of an existing font string by doing the following:

    1. Select function SYMBOL.
    2. Select menu option FONTS.
    3. Select a text string.
    4. Select the fill option for the string (NORMAL, FILL, HATCH45, or HATCH135).

 

FK Type Changes

Custom Areafill Patterns

You can design your own patterns for areafill. You create the geometry (lines, arcs and circles) for your pattern on a detail page. The following menu options under /AREAFILL/ /USER PATTERN/ allow you to visualize the pattern, store it. and recall it to modify it.

/VISUALIZE/ allows you to see what the pattern will look like when it is repeated.

When you are satisfied with the pattern, use menu option /ACCEPT/ to accept it, give it a name, and define shift, angle, and scale parameters (just as you can for system-defined areafill patterns). The next time you apply an areafill to a bounded area, the new pattern will be available on the USER PATTERN list displayed when you select the USR-PTRNS command bar button.

/RECALL/ displays a list of user-defined patterns. When you select a pattern name, the system copies the pattern design on a detail in your model so that you can modify its name, parameters, or geometry.

Default Areafill

For each CADAM Drafting session, when you first log on, the default fill is HATCH. After you select a pattern from the USR-PTRNS or PATTERN lists, the pattern you select becomes the default pattern until you select a different one or log off.

 

FK VDS Change

MCL Batch on NT

Provides batch capability for the math Constraint Language on CADAM Drafting-NT.

 

FK Window Changes

Visual Compare

Visual compare allows you to compare two models interactively to ‘see’ the differences between revisions.

 

System Changes

EDIT feature (cut/copy/paste) as a movable pallet on NT (Windows only)

This enhancement removed EDIT from the command bar and makes it a windows dockable toolbar.

Add downward pointer and simple tracking cross cursor styles

The simple tracking cross and downward pointer cursor styles are available. Host CADAM compatibility.

Mouse buttons reconfigured - (Windows only)

The mouse buttons on NT (for a 3-button mouse) have been reconfigured so that ‘indicate’ is the middle button.

Optionally perform auto-refresh (F3) after erasing

This enhancement allows an installation to choose if they want an automatic re-fresh (F3) to be performed after each erase operation in FK SHOW. Enabling this option would solve the problem of "raster holes" on the display after erasing elements from the model.

Line-on-line for NT (Windows only)

Line-on-line will display overlapping geometry in a unique and user-definable color.

Enable CADAM Drafting to support mixed-case drawings names - UNIX

CADAM Drafting supports mixed-case drawing names.

Simplified Chinese on AIX

Simplified Chinese is now supported in the CCD AIX product. The implementation uses the character stroking as supplied from graPHIGS since graPHIGS is a pre-requisite for all CCD AIX environments.

Simplified Chinese on NT

Simplified Chinese is now supported in the CCD NT product.

 

 

Data Transfer Changes

ICF Security

Full support for UNIX security through ICFTRAN (UNIX Server) is now available. User must key in a valid userid and password.

Filename reserved character mapping

Mapping table to provide a solution to the incompatible drawing name characters on NT (e.g., forward slash, backward slash, asterisk). By default, these characters are mapped to underscores, however the user may specify an alternate mapping.

DTTAPE port to HP

DTTAPE is the facility that allows a customer to mount a Host Nurestor tape and "read" it into CADAM Drafting.

Add switch to Data Transfer to optionally keep upper case drawings characters

Full support for mixed case drawing names (V3R3 only).

Retain RO flag when transferring models

This enhancement will preserve Host read-only (RO) flags when these models are transferred to/from CADAM Drafting.

Batch Data Transfer

PTF 1 adds CADTRAN back into CCD for UNIX only.

Simplified Chinese to/from Host CADAM

This enhancement insures that Chines characters are correctly mapped going to/from the host via ICF, data transfer, etc.

 

 

IUE Change

IUE GROUP/USER concept

A user may specify a full path (256 characters) for calls to U1OPEN and U1FILE for models not in a group,user formatted directory.

 

 

Raster Changes

Mirror

This option allows you to mirror a Selection Set across a line, with the option to keep or erase the original Selection Set in the process. You can use an existing 2D line or create one as you need it.

Cut/Copy/Paste

These options allow you to cut or copy a Selection Set from a raster image to a "clipboard" and then past it into another raster image in any model. The clipboard is an external raster file whose name you define.

Refine/Resize

This new option allows you to enlarge or reduce a raster image (that is, the boundary of the raster image). You define a new boundary by defining opposite corner points of a box.

Enlarging a raster image gives you additional space for creating new or relocating existing raster elements. Reducing a raster image decreases the amount of memory required to store the model.

Draw

You can add new raster elements to a raster image. This option allows you to draw raster circles, arcs and lines by defining the following:

To draw a: Define:
Arc   Center point and two endpoints, or three points
Circle Center point and a radius, or three points
Line   Two endpoints

You an also define the line width for the elements you draw.

Vector to Raster Enhancements

This feature will allow the user to convert vector lines, arcs, circles, ellipses, splines, offset splines, linear splines, conic splines, multi-lines, rectangles and breakout to raster data (this was only permitted for lines and arcs in V4R1.6).

Identify active image

This feature allows the user to traverse the raster images in a model, making each of them active, one at a time. This allows you to locate blank images, which you can them modify or delete. The active images are identified with a red, dashed border.

ELCADD Image Import Support

ELCADD is a US Navy flavor of the EDMICS raster standard.

Improved Storage Capability for Large Raster Images

Raster models created or modified in this release will be stored in a new format that enables large raster images to be handled more efficiently. Because the new format is different from previous releases, models stored in the new format cannot be called or modified in some of the previous CADAM Drafting releases. See your CADAM Drafting installer or system administrator for additional information.
