rebuild/macro question

I have written a macro that queries a couple of sketches within an assembly for coordinates and a couple angles. The equations folder has a degenerating dimension ( d1@sketch1=d1@sketch1-.01). After getting the initial information I force regen the part from within the macro and loop through many times. I tried driving the degenerative equation by smaller increments ( ie .001 ) to get a higher resolution result set, but at about the 289th forced regen, values quit changing. Editing the equations results in an incorrect syntax message ( although syntax is in fact correct ). The only way to recover the useability of the equations is save and exit sw, then restart sw. I have worked around the issue by breaking the area up into smaller segments and working each individually, but its a pain to do so. My question is this. Is it something within SWx limiting the number of forced regens or is it perhaps a limitation of VBA that I am running into?

It would seem that you are constantly making d1 smaller. At some point you have to have a condition that will stop the iteration when it gets too small. SW has a limit as to how small a dimension can be. SW also has limits regarding automatic relation tolerances.

See ship in a bottle for how to control dimensions to keep them from getting too small, too large or within a certain range.

Its not that d1 becomes invalid at some point. With the step distance set to .01" it sucessfully traverses the full range of motion in 250 steps. I can also traverse full distance at .001" steps provided that I do it in smaller sessions that do not exceed 280ish rebuilds.

From + 2.5" to 0.0" can be done in one session of 250 steps with a step distance of .01" sucessfully. But to do .001" steps, I have to traverse from 2.5" to 2.25" by .001" increments. Exit SW completely. Do 2.25" to

2", exit SW. ect.

Somewhere there is a limit that I am running into. Maybe a limitation of a character buffer or something. Just not sure if its a SW one or VBA one.

SP3 to sw2005 seems to have fixed the issue although I saw nothing in the fixed sprs concerning macro/equation funtionality.

Wouldn't know if this was a SW limitation (would suprise me - most of my models would get rebuild heaps more that 289 times before I am done) or a VBA limitation (how could it be?)... BUT...

If you are running a macro anyway, why don't you just look for the dimensions with name "d1@sketch1" and increment it as a part of your loop?

Can I ask what you are trying to achieve?

Not a programmer and could not figure out how to increment from within VBA , but figured out how to force a regen.

Was doing stuff with SWx for which it was not intended, sorry I can't elaborate.

I have re-used the macro several times and it works fine on 2005 sp3 ( work pc). Originally I wrote it and tried to used it on my home PC (2005 sp2). I only have the issue at home. This weekend I'll apply sp3 at home and see if that fixes it there also.
