Fluid Volume command/Space Claim volume extract

[Anonymous]

With the "Fluid volume" command or some other command is there a way to extract the inner volume of a part and create a solid body from the part interior? Space claim has a feature called "volume extract" that can do it quite nicely.

When i click on the inner faces of a part, "fluid volume" will not do anything. When I click on the entire part. it gives me a bounding box which is not what I am going for. I just want to get the volume underneath the part.

I am not familiar with the term Fluid Volume,  

You say say you are using the command, do you mean our Shell Command?

Or the Combine Cut?

Would like to help out, but .....

thanks for the reply, in "model" mode go to "Create" and scroll all the way to bottom. The "Fluid volume" command is there.

Not in my system, (Hobbyist or Start Up version).

this is what fluid volume looks like. This command is great for injection molding but not for vacuum forming. That is what I am trying to figure out.

Can you show a little more perspective in your model? the head-on view makes it impossible to determine what the shape really is.

I suspect that you need to cap off any open area with a patch and then run the boundary fill or fluid volume commands, but without seeing anything I can't be sure.

It's for a vacuum forming mold. Fluid volume creates a bounding box but what I really want is just the volume underneath the part.

I still can't make out exactly what you have there, but hopefully this will give you an idea of how to apply it to your design.

I don't have Screencast on this machine, so step-by-step photos will have to suffice for now.

1. Here is my vacuum molded part.

2. Next I switch over to the PATCH workspace and then use a boundary patch to "cap off" the bottom of the volume.
 

3. Next, I switch back to MODEL and invoke the fluid volume command. Notice I stay on EXTERNAL to start with - this allows me to select both the solid and the surface at once. If I immediately switch to internal, I will have to pick individual faces (a pain).

4. I swap over to INTERNAL and there we go!

5. I changed the resulting solid material to a bamboo so that you can see it through the translucent form.

6. To round us out, I hid the patch surface and moved the resulting solid out for clarity.
