Threaded hole not working in Part Design #248

Closed buteomont closed 3 months ago

buteomont commented 3 months ago

Something has broken about threaded holes in the Part Design workbench.

I started a new project, added a body, created a simple 40x40mm square sketch, and padded it to 40mm.

Then I selected the top face and created a simple circle sketch upon it. I pressed the Hole button, and chose the ISO metric fine profile. I selected the Threaded, Model Thread, and Update view checkboxes.

I set Size to M22x1.0 and Drill point to Flat.

The hole was there but the threads never showed up on the model. When I pressed the OK button, a modal window popped up with "Input error" and "Removing splitter failed".

I'm using development version 0.22.0dev (FreeCAD_weekly-builds-37668-conda-Linux-x86_64-py311.AppImage) on Ubuntu 20.04. This problem does not occur in version 0.21.2 (FreeCAD-0.21.2-Linux-x86_64.AppImage)

FWIW, I'm just learning FreeCAD and the more I use it, the more I like it and appreciate the power within. Kudos to the creators!

You can not create a Hole from Pad in any version of Freecad. You must select a face, create a new sketch, draw a circle, position the circle, close the sketch. Select this sketch and make what hole you desired.

My apologies, I think a lack of sleep has muddled my brain. A problem exists, however. I have updated the original post with the correct steps to show the problem. Basically, the hole shows up but not the threads, and an error is generated.

No problem. You’re welcome. Also, I am new in Freecad, I learn every day something new. Let me have a look at this problem. My gratitude goes to this marvelous community around the globe, that work very hard to make this wonderful software and keep it free.

A clue: I discovered that if I modify the hole to pass completely through the cube (by adjusting the depth or selecting Through all) the problem goes away.

As a side note, selecting Through all sets the hole depth to 139.95 mm for some reason, even though the cube is only 40 mm thick.

Another clue: It seems that the problem also disappears when I set the hole's Refine value to false.
