united extrude using sketch which touches the body in one point
(OP)
Hi,
I have to reproduce a model formerly made in Pro/E. I got stuck at one point, the picture says it all. The error message is simply 'unable to perform boolean'.
Is there a workaround for this NX limitation?
Thanks in advance:
Attila

Only workaround I would see is to leave a .0001mm gap on the line contact.

maybe that much difference wont be a trouble; but then again, I thought there is a known workaround.

Technically, the glass is always full.

BTW, what makes them non-manifold is attempting to create a model where more then two faces share the same edge. The simplest example of this is taking a rectangular pad 100mm square and then creating two 50mm square blocks placed on the top of the original pad and then attempt to Boolean unite the first block to the pad and then the second 50mm blocks, as shown below:
This Boolean will fail.

To an Engineer, the glass is twice as big as it needs to be.

Say I want to create the part in your image, but with an edge blend where the model is now false. Is there a possibility to temporarily create this false part and "un-falsify" it by adding the edge blends?
Or do I have to start from a blended sketch and extrude that?

of course the goal is not that the part to be impossible to manufacture. There are steps after that, so that edge disappears in the end. To be honest, I was trying to make my life easy when I decided to follow the steps as they are in the the ProE version of the model.
I'm sure there are other ways to achieve the final geometry, I'm just new to modeling, and need to know what can be, and what can't be done.
Thanks for all of your help, have a nice day!
(still interested in John's answer though)

Note that there has been discussions over the years about providing a temporary non-manifold state which could be used in a situation like above where the next step was to add a blend thus resolving the invalid state, but we have not done anything yet, but it's still on the table.
