Objects drawn with AutoLISP can't be selected

Under Acad2000i, an autolisp routine I use draws a section cut arrow and prompts for and draws the section number. Until recently it worked fine but for the last two days I have been unable to select the last two items it draws, an arrowhead (a pline) and the section number until I close and reopen the file. Auditing makes no difference...what could be the problem?

The AutoLISP routine draws with the PLINE command and writes with the TEXT command.

 

I've had similar problems when doing this with attributes. In my case the
textstyle or part of the attribute entmake function had an error. The sub
routine never completed so the end block function never got called. I would
be left with a circle & a line through it but no attributes. After I
reopened the drawing I could select the circle & line as a block but no
attributes.

you may need to do an array.

Fixed the problem. Turned out it was related to a setting called plinetype. Somehow plinetype had become set to 0. After setting it to 2 - the recommended or default setting - the routine worked just as it always had. It's a bit of a mystery how plinetype got set to 0, but I have altered the problem routine to set plinetype to 2 before drawing the polyline.

If you're curious what plinetype does, I suggest you look it up in your AutoCAD help where it is explained clearly in as few words as possible.

I don't see why it would have affected the routine but it did. Seems like an AutoCAD bug to me (2000i).
