Part has Null shape

Post by vpeppers »

I am having a problem in this massive project I am working on. On one of my parts, I can't seem to get a datum plane attached. My version info is:

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: English/United States (en_US)
Installed mods:
* AirPlaneDesign 0.4.0
* Assembly4
* BOLTSFC
* Curves 0.3.0
* dodo
* fasteners
* Manipulator 1.4.3

Here is what the treeview shows:

Capture.PNG (5.59 KiB) Viewed 4618 times
The report view has the following error message:
PartDesign::Plane: Link(s) to object(s) 'CopyPocket158' go out of the allowed scope 'DatumPlane842'. Instead, the linked object(s) reside within 'N/A'.

The treeview of the part that I am trying to use as the face to attach to is this:

I really have no idea why this is happening, and don't have a clue as to how to fix it. I have tried creating a new part, but the datum plane does the same thing as the other part. I need some help.

Here is the file:

I can see the file, but I cannot download it.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.

A lot of DatumPlanes have problems.
Please provide a MWE (minimal working example) : no Techdraw, no useless parts.

I was able to download, but I could not open the FCStd file. Crashed again and again.

I looked into the structure of the file and it is ridiculously enormous. There are more than 10,000 elements in the FCStd file.

It appears that a large complex assembly is being attempted in a single model file rather than using assembly techniques.

I'm lucky to open your 24.5MB file containing dozens of containers and hundreds of Body, it's not serious
a single faulty object causes a general crash, with hundreds of hours worked
there are useless DatumPlans at fault, no way of knowing why, it seems to me that they refer to neighboring objects that have been modified or deleted

For the datumPlane 842, you must remove the link to the Pocket 158.
In property/Attachment/Support ...
Once done, refresh and there is no longer a red exclamation mark
Your FCStd file is very bulky with many bodies.
It's beautiful airplane.
Good luck for the future
