How to export surfaces and sketches without solid bodies

Igor Fomenko Jan 17, 2018 3:54 AM

I want to export midsurface model to STEP file.

Solid bodies are hidden in shell configuration, but I get STEP model which contain both: hidden solid and midsurface

Of course I can delete (not hide) body in shell configuration but in this case I loose all mates in my assembly in shell configuration

Iges works good for one part, but for shell assembly I get the same situation.

Is there a way to export only surface. It is possible to use other format.

Hi Igor,

There are a couple of ways of achieving this. You can use delete bodies command to remove the surfaces you don't want, then export to step after this. Or you could use insert in to new part to save the body you want in to a separate file, then export to step from there.

Thanks, Kyle

  I need to hide BODIES, I found one way with iges
  Only last item gives shell assembly without solids.

    Igor,
    
    Are you working in an assembly or multibody part environment?
    If in an assembly, open the part and export from the part file using the method mentioned above?

I don`t understand for what reason is this dialog if it doesn`t do nothing in case I say NO

Igor

I'm not sure if this will help, but you can copy surfaces from one part to another in the assembly using offset surface 0.

Create an export configuration and delete the bodies you don't want to export.

Guys, thank you, please read carefully, I have assemby with two configurations: solid and shell (for export), I dont want to delete or supress bodies (in this case I loose mates). I export this shell assembly and fortunately only iges and only with Bounded surface option gives me desired result.

  Could you attach the files? Or recreate the problem if you don't want to?
  
  Another thought could be to add a new empty part to the assembly. Edit this part within the assembly and copy the desired surfaces. Then you can open this part file separately, containing only the required surfaces and export to step. This can then be suppressed in the assembly.

IGS doesn`t export sketch geometry, strange it has option for this
but fortunately STEP does.
So I will use IGES for surfaced assembly and STEP for sketch (wire geometry), for wire geometry I use separate part created in contex of assembly and export it separately from assembly.

  Hi Igor,
  
  You need to set your iges import settings "Free point/curve entities" to enabled and your sketches should come in.

    Thank you, I forget about import options, but I try to import not from SWX, STEP is OK without this option

    Do you know how to prevent step export from tranferring of solid geometry?

      Hi Igor,
      
      If you work with parts then simply add a delete body feature before you export the file. If my parts are part of an assembly then I simply
      batch all the parts. Adding the delete feature without saving gives me the assembly with all surfaces. If you are concerned about mate issues, then I would suggest you fix all parts in the assembly and suppress the mates before you export it out.
      Exporting out cuts the parametric link anyways. Not sure if Simulation software has the ability to update modified dumb solids as SW has introduced with 3Dinterconnect.

        OK,thank you, I know these workarounds, I wanted to publish ability to dont export hidden bodies for TOP TEN but some guy (may be Deepak) said that it is already done by this dialog
        but unfortunately it doesn`t work. Hidden bodies export anyway for STEP and only IGS works right.
        Moreover if you answer YES you'll get a lot of enveloped parts and subassemblies (SWX18.0).
