December's Lisp of the Month

TSTYLE - Text STYLE changer 

First you are asked for a selection method:

...selection method...[Global/Select] ? :

Global selects all mtext and text in the drawing to change
Select allows you to select mtext and text in the drawing to change

After selection you are asked to pick a text style from a dialog box mtext and  text is changed and moved to "TEXT" layer.

DSTYLE.LSP - Dimension STYLE changer

 First you are asked for a selection method: 

...selection method...[Global/Select] ? :

Global selects all dimensions in the drawing to change
Select allows you to select dimensions in the drawing to change 

After selection you are asked to pick a dimension style from a dialog box; all dimensions are changed and moved to "DIM" layer. 

DSTYLE.LSP just changes the dimension style by using the AutoLisp function (entmod).

All units, location, and orientation parameters are preserved. 

NOTE: If you use DSTYLE.LSP to upgrade a dimension from an older version AutoCAD to a newer version the dimension and it's text may move. Newer versions of AutoCAD use a different method for determining dimension location and orientation. You can use GRIPS to move the dimension where desired.

ASTYLE - Attribute STYLE changer

 Text height changing is currently disabled, if you want to enable it remove the semicolons in front of all the "grayed-out" text height code, marked at the end of the line with  ;text height code 

First you are asked for a selection method: 

...selection method...[Global/Select] ? :

 Global selects all blocks in the drawing to change
 Select allows you to select blocks in the drawing to change

 After selection you are asked to pick a text style from a dialog box; all attribute text is changed and moved to "TEXT" layer.

September's Lisp of the Month

The Dynamic Dialog Distance allows you to pass results transparently, with dialog box interface, to internal active AutoCAD commands.  To execute the command within a command, use 'DDD.  First, you pick two points. Then, pick the button to pass the associated information to active AutoCad command.

August's Lisp of the Month

The Dynamic Dialog Calculator routine allows you to pass calculation results transparently, with dialog box interface, to internal AutoCAD commands. To do this you can type "!RSLT" at the command line to use results in internal AutoCad commands.  To execute the command within a command, use 'DDC.

VP Scale adds scale annotation in Mtext, style TITLE (font Swiss 721 Black Extended BT) 3.5mm high, in layer VP-TEXT, 7.5mm below paper space view port, centered to view port.  User can then edit to add view port annotation.  Text height can be adjusted to desired size by changing code at line 47.

The Dynamic Coordinate System routine allows you to transparently input coordinates via Cartesian, cylindrical, or spherical coordinate systems, with dialog box interface, to internal AutoCAD commands.  To execute the command within a command, use 'DCS.

February's Lisp of the Month

Provides an additional snap to return a point perpendicular to a selected point, either in a horizontal or vertical direction from another point.  It is usable in any edit command requiring snap points, but has to be invoked transparently while command is active by issuing the command (perp_pt).

Example shown at right to demonstrate moving a rectangle perpendicular to a picked point.
