Rounding up drawing deviations

Assaf Ben-Nun · July 6

My drawing has accumulated tiny deviations - at the level of 4 digits after the decimal point (the drawing is in centimeters).
When I zoom in, I can see several lines adjacent to each other, instead of merging into one line.
does anyone have an idea how to handle this issue, using the program commands ?

With OPTIMIZE you can force correcting small deviations in angles or dimensions.

Thanx, Zoomer !
i was not familiar with this command - looks like the right procedure for me.

problem is the program keeps crashing while running OPTIMIZE (on the entire drawing, and also when selecting specific entities).

it's not a too heavy file (1.8MB), there are quite a few blocks inserted (and hatches, and some XREFs, which i unloaded before OPTIMIZING).

do you have an idea/experience as to what can cause the crashing ?

I don't know what causes the crash.
I think it needs to file a Service Request.

I often got files from clients to underlay, unfortunately with similar accuracy issues as your example. So you avoid to snap to these as issues would multiply over your 3D Model. Therefore I think Bricscad's OPTIMIZE tools are absolutely genius and I have never seen something similar anywhere else.

Unfortunately since I got OPTIMIZE, I did not get sent such problematic files so far. So I did not really test it on large real files, only small examples. And for me it worked at that time.

But at least since V25, or when similar genius Drawing Health Tool was implemented, I have similar problems.
I was never ever able to run through the whole cycle of Drawing Help. It will always abort at AUDIT3D stage.

But for me on Mac it does not crash Bricscad.
It will just show an AUDIT3D error in Command Line immediately and then Bricscad is frozen. Menus open but are grayed out.

If it was a smaller file, Bricscad may come after back many minutes, but is usually a bit quirky and likley unstable, so should be restarted.

The newer behavior in latest versions is more that Bricscad stays frozen and has a memory leak soaking more and more memory and it is better to force quit Bricscad immediately.

Interesting is that in most cases I can still File > Quit Bricscad normally nevertheless and even save the file.

thanx for sharing !

i am using V22, 2D only, and honestly say it is MY file - and not (bad, bad….) others' that has grown these deviations (which multiply themselves over time ….).

i experimented a little with OPTIMIZE, and found out that when isolating a layer, for example, and optimizing it's entities alone (excluding blocks) - it works alright. only the issue for which OPTIMIZE is needed crosses layers, so…..

i am using a quite an old DELL laptop - maybe it's rather 'poor' resources cause BC to crash.
tried to run it on stronger desktop station of ours - there we have a V18 Bricscad, which doesn't seem to have OPTIMIZE introduced (even though web&AI search insists V18 already have OPTIMIZE included)
