Assembly cuts

Hi all,

i am working on a project for a customer who makes a lot of assembly level cuts, & things are made more difficult than they need be, because it would appear that you are limited in controlling the depth of the cut. You do not appear to have all the options you have at part level, the selected surface & next surface options are not available at assembly level, which like i said already, is making life difficult for me.

The question is, am i right about this? am i perhaps missing something, up until now i have not really made cuts at assembly level. Is there a way of making these options available? I have an advanced assembly license, but that doesn't seem to make a difference. For the record, i am working with Creo Elements/Pro for this project.

John

I don´t think it´s a good idea use assembly cuts. In our company it´s prohibitted use assembly cuts.

Top-down design:

It´s better publish "key geometry" into each part part and use this geometry for feater creating.

Bottom-up design:

Make/create some logical and standardized method of creating featers, that are "common" for more parts.

I think the key statement for John is that it is his customer that makes the assembly cuts so he can't dictate this upon them. He is just trying to simplify or make things easier if possible.

There are still 4 options in Creo 2.0 for assembly cut depth. In this example, it allowed me to cut to the assembly datum plane. What I don't have is projection onto a face and a few others.

As for assembly cuts... absolutely valid! One of the best upgrades ever! When you do a lot of parts with secondary operations between detailling steps, you cannot live without it. For me, this is always driven by the drawing requirements for the project. Think of piece parts detail drawings>next level fabrication assembly drawing>subsequent machining operation drawings.
