CAVITY FILLING 1

[proEdj]

I have a complex cavity in one part and would like to generate a new part that has the same geometry as the cavity. I imagine that this procedure is very common in mold design...except instead of going from the mold positive to the mold, I already have the mold and would like to create the part in which that mold will produce. Any ideas?

Thanks

In Mold Design you could create an item called Molding. It will create a Pro/E part from the cavity tool geometry.

You need to copy the inner surfaces of the cavity into a new part.

In WF2: (The process is the same in 2001/WF, but the interface controls are not)

Select a surface inside the cavity (so that it is highlighted pink). Then, hold down shift and select the flat face of the mold. Release shift, and all of the surfaces inside the cavity should be selected. (This is the seed and boundary selection method. The first surface is the 'seed', and Pro/E selects all surfaces adjacent to one another, starting from the seed, until it hits the boundary, which is the second surface you chose).

While these surfaces are selected, copy and paste them into a copied surface feature. Then, you can use one of a few techniques (copy geoms, or straight copying and pasting in a ghost assembly) to copy the surface into a new part.

Finally, you will probably need to make a flat surface (Use Edit-->Fill) to close off the surfaces. Merge these together to form a closed quilt, and solidify them. You should now have a part which exactly matches the cavity geometry inside your mold!

Hope it works

If your initial part is a solid then just make an assembly into which you place the part with the cavity. Make another part big enough to more than fill the cavity and assemble that to intersect with the part you've got.

Use Edit --> Component Operations --> Cut Out to cut away all the intersecting geometry between the part with the cavity and the new part. You'll be left with the original part with the cavity and another part that fills the cavity perfectly.

This seems like a very easy operation, however in my assembly the components automatically become packaged during mating and this prohibits me from using the "cut out" function in COMPONENT ==> ADV UTILS ==> CUT OUT. I am using pro-e/2001, which I did not make clear earlier and there is no "cut out" option with-in this program.

Thanks again

2001 does have this option, I've used it several times.

Assembly -> Component -> Adv Utils -> Cut out are the menu options as far as I remember.

I'm not sure what you mean by the components becoming packaged though. You should be able to asemble them together, make the cut and then open the cut part seperately.

It might not be such a good idea to use the cutout command in your overall assembly (i.e. in the top-level mold assembly), especially if the mold halves are not fully constrained.

Try to create a new assembly with just the cavity component and the block from which you want to make the cutout. Assemble them to each other, ensuring that the block is fully constrained to the cavity.

This should allow you to use the cutout tool.

If you still can't use it, you might not have the right licensing for this technique. If that's the case, use the copied quilt method I mentioned above.
