Re: Intermittent constraint solving problem in sketch rectangular array.

Hi All, If anyone is interested, and in case anyone in the future is looking for similar answers, I have managed to solve both of my problems! Firstly, the issue with the constraint solving: The answer was to perform a recompute() BEFORE calling addRectangularArray() Here is an example: https://gith...

Re: Intermittent constraint solving problem in sketch rectangular array.

Just an update on this as I got a bit of free time. I tried with the latest build on MacOS and it still proved intermittent (e.g. 0.19 21514) I can see one thing I could do is try and constrain the angle of the lines that are 'flipping' i.e. currently I constrain them to parallel to a construction l...

Re: Intermittent constraint solving problem in sketch rectangular array.

Unfortunately as much as I tried with the following three builds I couldn't get your macro to create the faulty sketch. Hi Syres, Thanks for the effort in trying, I must admit I wasn't expecting anyone to try it out from the macros... and therefore I didn't say :oops: that the offending code is on ...

Intermittent constraint solving problem in sketch rectangular array.

Hello, I have successfully been using the python API in a macro to create lego brick models derived from sketches. https://github.com/vectronic/freecad-legify-macros I've come across an issue in using "addRectangularArray()" in Sketcher. Intermittently (perhaps 1/3 of the time) some of the copies of...

Re: Techdraw dimension between line and arc tangent

Thanks for getting back to me.

Simpler example attached.

In the screenshot below, I get an error when I try to apply a fillet to the two selected arcs.

Re: Techdraw dimension between line and arc tangent

Thanks for reporting! Thanks for implementing! I have taken the useful advice in this thread and re-done the sketch as two arcs and this indeed lets me add the desired measurement in techdraw. However it has has lead me to another unexpected issue in part design.... Now that the 'stud' is created b...

The construction line doesn't contribute to the geometry as seen from the outside. You can create the circle from two arcs, that's what I did in my example. Similar with the line: split it in two tangential lines of equal length.
Thanks very much! Understood. I will give it a go.

Re: Techdraw dimension between line and arc tangent

@chrisb has it. When I need to do something tricky, I add construction geometry in 3D, then include it as Source for the View. You can always hide the construction lines with the line decorator. I have attached a screenshot of the sketch used to drive the geometry where I have a tangent constructio...

Re: Techdraw dimension between line and arc tangent

details please. :) I don't get a lot of feedback on the cosmetic functions unless they crash. With pleasure :-) I have recorded my actions here to add a cosmetic vertex -> maybe I am doing something wrong? As far as I can see this isn't desired behaviour and I'm sure it didn't work like this previo...
