Boolean Operation on solids

[krzysztof.psujek]

Hi, could anyone do an operation intersect of solids for me. I will be gratefull for it.

I use AutoCAD and during tries on a few solids during such operation got error "Solid is not valid...".

I've found on the forums that Inventor has a tools to handle with this issue.

Regards Chris

Are you asking an Autodesk question or Inventor?

If in Inventor what are you looking for?  What does this intersecting solid supposed to look like?

Also do you have Inventor?  If yes, what version?  Or do you want it as an AutoCAD file?

[krzysztof.psujek]

Hi I haven't Inventor so that is a reason I've asked for help here.

I need a DWG file as a result but think it is not a problem in Inventor or I am wrong?

In the drawing attached to my first post I 've describe 3 places that I want to get intersect and on the left side also describet with leader

a example expected solid - which was create with solids that I have no problem.

thanks in advance.

Well there was no file attached in your original posting.  So that's why there were so many questions..

I do not see any attachments.

Double Post!  Why?

Here's the problem..  You had two posting.  One had the drawing and the other didn't.

[Mark.Lancaster]

@JDMather  He had 2 postings..  The other one has the file attached.

[krzysztof.psujek]

I don't want to doubled it. During posted I've got freeze and probably 2 times pressed post button - and that is the reason. Sorry for that.

I've send information to the moderators before had any answer from you. 

Chris

EDIT: I've upload the file here, doubled post reported to admins

[krzysztof.psujek]

Yes, I've seen it before. Ok I will add attachment into second and this one report again to the moderators.

Are you sure you want the intersection?

Do you know the meaning of boolean intersection?

Or do you really want to subtract?

What are your intended units?  mm? m? km?

Is there a reason you are very very far from 0,0,0 origin?

Do you know that AutoCAD has trouble performing Booleans a long ways away from the origin?

[krzysztof.psujek]

it is a little mess now with doubled post... ehhh

I want to get a section of these cyan solids. 

I use for it intersect command in AC, and got right results. In two cases where 'boxes' crossing tube it should looks similar to the solid on the left side.

Third will looks different but the same operation should be done.

Units meters. 

[krzysztof.psujek]

I've read about this issue. And try change units, or move into 0,0,0 coordinates, also changed precision. And tried deal with it using conversions/exploding to meshes, surfaces and try to back to get solids. but all of this doesn't got me good effects. Always got message about wrong solid at the end.

[JDMather]

You have two openings in your cyan body that I will have to find and stitch.

[krzysztof.psujek]

Both cyan solids are corrupted.
I've got a lot of solids from the client but only with these two noticed such problems.

[krzysztof.psujek]

And do You get sth or I have to looking for another method to get it right?

My collegue tried in Microstation explode into shapes (3dfaces) later stitch into polymesh and also failed on convert to solid.

The geometry you have is rubbish - so I will have to remodel.

[krzysztof.psujek]

Fine, thanks for your effort. 

If it's a lot of work to recreate whole geometry - leave it.

Most important for me are only these small pieces that crossing with smooth boxes (two on a tube and one on other solid). Rest is not such urgent for me now.

Is something like this what you are after?

[krzysztof.psujek]

Shape of Solids looks OK only units and coords was wrong. But I handled with it.

You did this in inches but dwg units are feets so on first look I noticed sth wrong 😉

There is one you missed (the smallest one on "4_Schakt_Solid" layer). 

But it's a lot for me 🙂

Thank You very much!

Could you describe shortly steps you have taken to do it. 

If I get similar problems in the future I won't ask nobody for help only do it by myself.
