Solved: Re: Difficulties with region and bpoly etc

tcrish · ‎02-14-2017

Hello All,

I have a pesky file that I just can't seem to region. I did a pedit multiple to close it and it still won't region. I deal with a lot of vendors line so maybe this is the issue.

Can anyone take a look see and check if you can region it. I have been pulling out hair for a couple hours. I have had this issue, along with bpoly and pedit over the years which has been frustrating. I tried Wblock and Flatten as well....yoy. I can usually get things closed and regioned eventually but this one is nuts.

If it matters, I am using ACA 2014 on a Dell Precision T7500 Win7, Quaddro FX 4800

Knowing why it happens and how to fix it will make me happy....

Any and all help appreciated.

Regards,

Tom

Explode, overkill (just to be safe), delete the indicated arc and use fillet to recreate it. Then use mpedit, select all, and join them with 0 fuzz.

Thanks Prof D,

That worked great. As you can see there are tons of entities so what clued you in to that one radius?

Inquiring minds need to know....lol

Thank you fine sir.

I checked to see if it was closed. It wasn't.
Then I closed it and reattempted the region. It didn't work.
- There are a couple of reasons that regions don't work
  - non-closed shapes.
  - overlapping segments
  - zero-length lines
I exploded, ran overkill and then used mpedit to join. It was still open.
I forced the close on the properties palette and exploded it and looked for a very small line length using qselect.
It happened at the location I indicated where the first and last segment of the polyline were.
I assumed that there was some misalignment so clicked on the arc, got the radius, deleted it and filleted.
Then mpedit and it closed properly. Then region works.
