For July, Harry's picks include the following:
Circle to Polyline and Polyline to Circle — Kent Cooper — Two complementary functions in one LISP file: the first converts circle entities to polylines in AutoCAD; the second converts polylines to circles.
Show and Hide Toolbars — Leonid Nemirovsky — Len created a function to display one or more toolbars on the drawing screen in AutoCAD, but he added a twist: as soon as the user picks a command from the toolbar, the toolbar itself disappears.
Add New Lines to Existing Text Objects — Alan J. Thompson — A2T allows you to add a new line of text to an existing text object in AutoCAD. At first glance, it may seem a bit trival, but this routine applies the properties of the existing text entity to the newly created text entities.
Restack Text Entities — Raymond Rizkallah — This routine is designed to rebuild a paragraph of text entities in AutoCAD that are scrambled. The selected text is copied to the new start point, lined up, and stacked according to the spacing factor, while existing text properties are maintained.
Erase Block Components Safely — Leland Leahy — An alternative to the normal Erase command — it filters out xrefs from the selection so that they are not erased.
Convert ATTDEF Entities to Text — Robert L. Zipprich — This routine cleans up the unwanted ATTDEF entities left behind when an attributed block is exploded with the regular AutoCAD Explode command. It achieves this by converting the unwanted entities to text.
