### Re: Union of threads and cylinder "Shape is Invalid"

I hear you, and it is to be expected with software which is still under development. I wish I could find that one method that works for all scenarios, but if it these quirks are known issues that go deeper, than so be it. ;) Regarding the helix, I used an old script which will sweep along a path. He...

### Re: Union of threads and cylinder "Shape is Invalid"

Gotcha, but it still doesn't make sense. This a bug or a rule? The 2nd example I attached was based off of two sketches. One for the large cylinder, and then a second one to pocket an outer ring using the same face as the first sketch. Why wouldn't that variation work? Perhaps the Boolean function d...

### Re: Union of threads and cylinder "Shape is Invalid"

why do you still have coincidences with a sweep end and the seam edge of the cylindrical face! I proved to you with that last iteration that, that is a problem condition. 1 closed boundary per sketch. Hmm.. I don't know what to tell you. I mentioned in my last response that I tried all the techniqu...

### Re: Union of threads and cylinder "Shape is Invalid"

Or so I thought. I went the next step further and pocketed an outer ring from the cylinder. I then tried all the techniques mentioned above, but continue to get Invalid Shape.

### Re: Union of threads and cylinder "Shape is Invalid"

That worked. I also tried changing the helix length such that it does not complete the last coil at the same location as the start (basically, instead of wrapping 6 complete times, I had it wrap 5.9 times). I could then do a CUT without a problem, but FUSION still showed invalid. Not sure why it is ...

### Re: Union of threads and cylinder "Shape is Invalid"

I searched for "Invalid Shape" and could not find any valid explanations that matched my situation. I'm not as much concerned with how to create a screw. This thread was more about why I'm having an issue joining two separate objects and what causes the Invalid Shape issue. Attached an exa...

### Union of threads and cylinder "Shape is Invalid"

1. I created a cylinder 2. Created a sketch on the side of the cylinder of a triangle 3. Created a new helix sketch wrapping around the cylinder with a decent pitch and length 4. Ran a macro which extrudes along the helix path - I get a nice thread like pattern, similar to a screw 5. I then try to U...

Just tried, same issue. You did reduce the errors from 8 to 2, so that is progress

### Re: Test request

Left with 2 errors during compile. Looks like linker issues. I do apologize if I'm doing something wrong here... Also, when I try to run it and create New, then change workspace to "Assembly", I get this error: "matplotlib not found, Plot module will be disabled No module named Assemb...

### Re: Test request

I'm getting both compile errors and run time errors. If the compile errors are causing the runtime (assumption), then I should fix these first. I thought I had the latest lib pack: freecadlibs_8.1_x86_vc9 Looks like it includes Qt 4.5.2 If there is a newer lib pack, please advise. I am not able to u...
