Re: Non-manifold issue.

I redid your file and simplified the sweep profile. The SubtractivePipe works. Check Geometry reports a valid solid. Was that just a change to the profile vertical distance constraint? tip radius and everything else looks the same as a few I have tried. Loosing track of which version is broken in w...

Re: Boolean visability bug 0.17

That works.

Thanks again :D

Re: Boolean visability bug 0.17

I see.
sort of.

Not really.

I can now see the rectangle. Or the cylinder.

How do I see both at once? Like in Part wb boolean.

Because I often do this to adjust placement of part and tool.

Re: Non-manifold issue.

I'm up to broken manifold 0.10 now. As mentioned before, I'm only saving every 3rd one. Thats approx 30 ways I have tried to make this shape that didn't work. Over 3-4 days. 6-8 hours a day. I hate to admit defeat, but this one is beating me. 30-nill For broken manifold 0.10 I thought I would revers...

Re: Non-manifold issue.

Facepalm!

The fc0.16 version is broken too. Its just very fine and took a bit to notice.

what is it with this shape???

Boolean visability bug 0.17

Hi guys. I think I found a bug, although will be surprised if its not know already. I've been seeing it, or more accurately, not seeing it for a couple of weeks now. To replicate simply make 2 bodys and perform a boolean in Part Design 0.17 Now make the boolean invisible and make the body within the...

Re: Non-manifold issue.

Finally got it to work. I took Normands good one and made a .step. ( I used Normands one because I'm more confident he didn't break stuff early in the tree :lol: ) Imported that to a new doc in fc 0.16. Made a new profile in Part Design. Made a new helix in Part WB. then used Part WB sweep and boole...

Re: Non-manifold issue.

Up to broken manifold 0.7 now. and I'm only saving every third one.. This time I tried exporting a .step of the good part, then adding the BSPT thread to that, a couple of ways. First by making a new body with a basefeature made from the imported step. This gave a message about the .step being a she...

Re: Non-manifold issue.

So I tried adding my 1/4 BSPT thread (why a 11-13mm tapered thread is called 1/4 is beyond me :?: ) to Normands file and it broke the manifold again. So I made the base solid from a revolve as suggested. That's defiantly a better way to go if file size is any indicator. Made the first thread without...

Re: Non-manifold issue.

Thanks for the great advice and modified file Normand. I had to put a 1/4 bsp thread on the small hole too and it broke my manifold again. So I'm doing it your way now. (I should have thought of trying a revolve!!) Fingers crossed. I was aware the thread sweep was not ideal. I'll be doing it with th...
