Re: strange rounding issue when setting Tip property of body

I looked at both of the "diff" files. From the second one (GuiDocument.xml) it seems that the camera angle was changed during the test. Therefore the colors changed quite a bit. The errors in the first file (Document.xml) are in the 15th and 16 decimal places. Are you serious about calling this a "s...

Re: PartDesign: setting Tip property leads to incompletely featured body

This has been discussed numerous times. Auto recompute is sometimes a big time waster. I tried your file and found the following. I opened the file, selected the body, changed the tip from Pad to Pocket. Immediately the model tree showed the need to recompute. It did not do an automatic recompute, b...

Re: 0.18 maybe a bug in PartDesign?

I had no problem recomputing, but Cylinder018 has an error symbol in the model tree. Looking at the Dependency Graph it seems that Cylinder018 is trying to subtract from nothing, i.e. no base feature. It is linked only to the coordinate system.

Re: Cant import files

Did you try the latest shiny version ? That's the one I — and many others here around — are using. Nothing wrong with realthunder's version, but it should strongly pointed out that this is a fork of the official version. It may not work the same as the latest official version. I do not think it is ...

Re: opencamlib and AppImage experimental function

I do not believe there is a standard user interface to add the experimental features.

Just create it yourself. Right click in the Path parameter area and select New Boolean Item. Call it:

EnableExperimentalFeatures

and set to true.

Re: elekscam & gcode don´t work

I think it is customary to use 4 spaces for an indent in Python, not 2 spaces.

Re: Sketcher WB: moving destroys hexagon

I think this is closely related to the mostly eliminated problem of "sketch flipping." Moving a short distance seems to work, even when grabbing a single element. Moving a large distance fails. If you read the wiki carefully it says nothing about maintaining the original shape, only the constraints....

Re: Offset sketch plane

The "Base" is referring to the datum plane that the sketch is attached to. That offset can only be changed if you go back to the datum plane itself.

Re: Circles not 3d-printing smooth

I looked at your FCStd file, and the shape looks a bit rough. It appears that you have the Tesselation at a coarse setting. Look at Edit >> Preferences >> Part Design >> Shape view. The "Maximum deviation . . . " in your file is set to 0.5%, which is pretty coarse. I keep mine at the minimum, 0.01%....

Re: Sketcher WB: moving destroys hexagon

The sketcher solver has no idea that it is a polygon, it just analyzes the constraints together with the move operation and computes a solution that conforms with the constraints. This is a really important concept that probably should be featured in the comprehensive tutorial Chris has authored. T...
