Render-Error after new Plane

Post by edgeHB »

Hey community,

i just started to learn FreeCAD yesterday but today i ran into a problem, i'm not able to solve myself. I used the search, but i probably don't know the correct lingo yet.

FreeCAD Version:

Code: Select all

OS: Windows 10 Version 2009
Word size of FreeCAD: 64-bit
Version: 0.20.1.29410 (Git)
Build type: Release
Branch: releases/FreeCAD-0-20
Hash: f5d13554ecc7a456fb6e970568ae5c74ba727563
Python 3.8.10, Qt 5.15.2, Coin 4.0.1, Vtk 8.2.0, OCC 7.6.3
Locale: German/Germany (de_DE)
Installed mods: 
  * A2plus 0.4.59d
File:
Deckenhalter_Lampe.FCStd
(44 KiB) Downloaded 12 times

Problem:
I created a Body based on two Sketches:
1st sketch = the "base"
2nd sketch = a pocket

looks good so far:

I now added another plane (according to this video: https://youtu.be/4uEwHB7LciA?t=720) and a third sketch on that plane, to create another pocket.

The first thing that was frustrating was, that the new rectangle for that (in Sketcher) was behind the existing pads and when i turned the existing pad and pocket off and only sketches on, the existing sketches were not drawn. So i had to "freestyle" the positioning and pocketing. (I'm sure that is a user issue ;) ).

The second thing is, that the 3D View of the body is destroyed and does not display, what (i thought) i drew. When i turn off the Pocket001, the model looks fine again:

I'm sure, that i did something wrong, but i would appreciate some help!

A full recompute of the whole model fixes the issue.

Concerning your sketches: To have less clutter on the screen and to better show the intrinsic geometry of a sketch, it is advised to minimize the number of dimensional constraints. See the attached file for examples.

Sketch : Map Reversed = true
or Transparency = 50% (Std_SetAppearance)

Pocket : Reversed box : ok
