Multiple cavity blocks

[mlandm]

I need to make a block with multiple cavities of the same part. I've read one post describing how to do this by creating a new part, wave linking in the single cavity part the number of cavities needed then combining them. I cannot get this to work. I create a new part, then wave link the original cavity in, but each time I do it is placed directly on top of the first one, and I cannot move either of them. If I wave link in one part I cannot instance it to get more. If I creat a new part and insert and existing part I can move them around and mate them but when I go to combine them everything disapears. Can someone tell me what I'm doing wrong, or walk through the steps one at a time. I'm at my wits end.

Would you not just create the first cavity (subtraction boolean) using the linked solid and then just instance/array the feature as needed?

If your using Mold Wizard, there may be a completely different way to do this as well. I'm not familiar with that product.

This is what I do before.

1. Create top assembly part
2. create cav part, cor part, parting line part, etc.
3. figure out parting line on the part and split faces where the parting lines is.
4. wave link the part to the parting line part. I usually do a region wave link instead of the whole solid, except when the part is really simple. If there are multiple cavities, then I create multiple region wave link and reposition them.
5. Develop the parting line surfaces, then sew all of them. I make sure to make the parting line surfaces larger than the block, and also to do an examine geometry.
6. Link the parting line sheet to the cav and core and the components then either trim the edges of the PL and do a patch, or use the whole PL sheet to trim the block.
7. Create the locks for the cav/core. You can create this in a separate part then link it to the core and cavity so that if you have to change the lock, it updates both cor and cav.
8. link the components to the core/cav then subtract.
9. Add blends,
10. Split surfaces of core/cav for clearance and vents

Good Luck!

I forgot.
Do the split for the clearance right on the parting line part and it would be automatically be present on the core/cav

Prior to linking the cavities into your new part you need to add an existing part (however many times it will occur in your finished cavity block), repostion them to their correct location. Then you can link them in and unite them.

You need to have all the parts you want to create the cavity assembled and component patterned and the create X number of wave links to get your subtraction feature you can assemble the X parts into one assembly and have a single wave feature of the assebled parts.

If you want to do a pattern the easiest way would be to wave one part and do the subtract.
Then do a pattern face array to copy the cavity face to other places on the block.

This will reduce the size of the assembly and speed regeneration.
