Trim/Unite/Subtract question
Trim/Unite/Subtract question
(OP)
I'm relatively new and learning.
I'm trying to create a dome on a block. I created the sketch to interfere with the block and then I extrude it longer than the block, see 2nd pic.
How would I unite both bodies but cut the trim/excess width and length of the dome so that it matches up?

RE: Trim/Unite/Subtract question
Why not Extrude whole the section you want rather than make them in 2 separate features and then trim them down? Is it necessary to do this in 2 steps? I've attached an example just using curves (no Sketches), but you can easily create a Sketch with the correct profile. See layer 1.
If you absolutely MUST do it in 2 steps, then look at the solid on layer 10. 2 sides can be trimmed using the Extude command, the other uses Trim Body using 2 planes of the base. Play around with commands and see what happens when you change the Trim direction.
There's more than 1 way to skin this cat....

But you may want to see my attached file using replace face. It was done in NX7.5.
You may not necessarily want to utilize replace face in this situation but it sure comes in handy for others.

RE: Trim/Unite/Subtract question
You need to step thru the model feature by feature to see how I did it. The two extrudes are united at the creation of the second extrude.
I used replace face (in syncronous modeling) to do the rest. You can swap out the end faces if the replaced face should have been to the other one.
Don't hesitate to ask more questions if you need to.
