Create internal volume from a solid model

[anand.kamdar]

I want to create solid volume/cavity volume of one part without using tools like Pro/Casting and Pro/Mould.


I know one way to do this is to copy all internal surfaces, fill open surfaces, merge all the surfaces and solidify it.


Is there any other way to do this?


Thanks in advance.

Build a block around your part and subtract your part from the block, then trim back the areas you don't want as part of the volume.

Create an assembly with the part and block using default
constraints.
> Activate the block from the model tree
>Insert>> Shared Data>> Merged/Inheritance
>Click Remove material
>Select the part you want to subtract> Done

Then as looslib says, trim the areas you don't want as
part of the volume.

and don't forget to use top down design to do it.

Thank you for response.


To trim the volume I need to copy the surfaces which I want to avoid. Without copying the surfaces is it possible to trim the volue?

You may be able to build the part in such a way to use analysis features to calculate the volume, but it depends
on your part.

If you can build it as a solid and then shell it or
remove the interior in such a way that it captures that
internal volume and that later features don't change that
internal volume, analysis features will work.

Build the solid and create an analysis feature to capture the part volume, Create whatever features needed to
remove the interior and create another analysis feature
to capture the part volume. The difference between the
first volume and the second is your internal volume.

You need to make sure you don't add additional
external geometry in between the two analysis
features as that will throw the volume off. For example,
if you were modeling a mug you wouldn't want to add the
handle in between the analysis features. However, if you
had internal ribs in your mug, you would want to make
sure they get built in between the analysis features.
