Topic: reactors on dwg startup

[jtoverka]

So I use the CUI to load a lisp file on drawing startup.
This lisp file has reactors that makes sure standard AutoCAD commands are compatible with AutoCAD Electrical. These functions work great. However, on some instances I open a drawing and I get the following:

; error: Unknown exception occurred
; warning: unwind skipped on unknown exception

I comment out the section with the reactors and these errors go away. These errors only occur during drawing startup. If I load these reactors when the drawing is active, no error occurs. Does anyone have any experience with this issue? There is a vaguely similar thread on this.

In my experience that is often associated with a memory allocation error. Strategic placement of (gc) calls, e.g. every nth iteration of a memory intensive processing loop, generally remedies.

I used this before and after loading the file and there were more errors. xD
So I placed them before reading reactor information, and after writing reactor information. I can confirm now that it works.  These intermittent errors are frustrating!

That surprises me.

Naw man, just part of the journey to reign supreme over the machine.

Glad you're on to your next challenge.

acadlspasdoc = 1
acad.lsp

Code - Auto/Visual Lisp: [Select]

1. (defun s::startup()
2.  ;; do stuff
3. )

Old school … run the lisp code after the drawing loads by loading acad.lsp with each drawing.
Another option is to enable VBA and utilize events like AcadDocument_Activate and AcadDocument_LayoutSwitched in Acad.dvb and then autoload it.

I use Appload and add my lisps to be autoloaded in the start up suite including reactor code.
