Surface to Solid

Hello everyone!

 

I am trying to convert surface objects into a solids. The issue is that, the objects are not precisely made with tiny gabs between the faces, making it impossible to use the SCULPT command to convert them from surfaces to solids. 

(Bellow, screenshot of the objects)

 

Is there a quick fix for this issue instead of modeling each object seperatelly?

Hi,

You can convert surfaces to 3D solids by extruding the surface with THICKEN command .

I realized that the objects are made form meshes instead of surfaces. Now, I am trying to convert the meshes to surfaces and than from surfaces to solids. 

 

So my next question is: Is it possible to convert surface meshes directly to solids?

would you try CONVTOSOLID (Command) , any changes ?

Would you like to check the file and see if you can manage to convert some of the mesh objects to 3d solid?

To be blunt, but have a lot of junk there.

 

What is the ultimate objective, i.e., why do you need solids?

Since you only have 3dface objects in your CAD drawing file , this is how to convert the 3D face to a 3D solid : 

  1. Enter CONVTOSURFACE on the command line.
  2. Select the face that you want to convert.
  3. Enter THICKEN on the command line.
  4. Select the surface .
  5. Enter a thickness value for the selected surface on the command line.
  6. When prompted, choose whether or not to erase the defining surface

click on below image to see how it's work .

Nope, sorry.


You could convert all 3DFaces to (planar) Surfaces (convtosurface) and then try to convert to Solids (sculpt), but ...


- none of the buildings has a floor (bottom closing surface). For each of the missing floors you have to add a planar surface. But, because they are at different Z-levels you have to do it separately for each building one by one - a lot of work.

- Often I see buildings which penetrate each other. This will cause additional problems.

- I didn't check if the the walls, the roof and the (self drawn) floors build watertight volumes. If not, you have to repair it - also one by one.

 

Summary: I don't see a way to convert the 3DFaces into solids without an enormous amount of work.

I want to clear the objects. As you said, there is a lot of junk in there and I am used to working with solids.

What is your end goal for the file?  If it is to generate rendering or take some measure ment you may not need to convert the file to solids.

I need it for axonometry view, using flatshot. Also, there are more thaan one face on top of each other making it difficult to render the scene.
