Full Version: How can I close this?

Hi - New to MoI and looking for assistance.

I have a hole that I want closed. Basically I would like to select the vertical profile on either side and just "slide" the gap closed.

I have been able to do so ( at least visually), and end up with a single mesh. However I don't think I'm ending up with legal geo, as when I do a boolean difference, the resulting mesh is open again.

Any tips? Thanks.

Before your Boolean Diff make a general Join on your pieces wanted to be booleanized

Better the next time to post your 3DM file!

Hey, thank you for your reply. I did that, to no avail. However, when I joined and then did a merge instead, I got the results I was looking for. Weird.

I will definitely post my file next time, and thank you again.

Hi Lee, yes that helps a lot if you can post your .3dm model file instead of only a screenshot. That then allows a close examination of your geometry and also tests on it neither of which can be done on just a screenshot.

It sounds like you've got this all set up ok but the main way to handle a case like that is to make sure the main object you are working on is a closed solid.

When you do a boolean on a closed solid then the "side walls" of the cutting object will be automatically left behind and you then don't have to do any additional work to close up such things.

When your base object is not a solid then a boolean difference will only cut up surfaces and not be able to form a solid result automatically, like you are describing.

The booleans are mainly focused on working with solids, they use which solid volume a piece is in to determine which areas to keep and discard. If your base object is not a closed solid then there are no volumes to work with and the boolean will only work as a surface operation instead.

Hi Michael,

Sorry, I just saw this, as I appear to have failed to subscribe to my own post.

I have attached the component that I was unable to close properly. I have since rebuilt the part, but it would definitely be nice to know what I was doing wrong.

Thank you for your help.
