Recalculate the document moves the Assembly constraints.

[dcapeletti]

Hi, could you please watch the video I made for a few minutes. https://peertube.video/videos/watch/fd5 ... c093217742

I'm using assembly 2, I create some restrictions, but when I press recalculate the document, the objects change places and I have to press the rubik cube again to recalculate the restrictions. Is this a bug or is it normal? Tell me if I'm doing something wrong.

I enclose the freecad document

Hi dcapeletti,
i had a look at your video. You are using A2 in a complete wrong way. You have to import all parts from external files to the assembly file and then use constraints to combine them.
Please find a tutorial here: https://www.youtube.com/watch?v=dhaYJKDk4GI

Now I get it, thanks for the video.

Basically I always have to use Assembly's import tool and apply the restrictions to them.

I wonder what happens if in a file I have more than two bodies in the same file and I import them with assembly?

Thank you

Another question. If I want to use a spreadsheet to get design data, the length. Can I only do it in the file that contains the body with the design or can I do it in the assembly file?
For example I want to get the lake of the object, can I do it in the assembly file?

Thank you

In generally, Assembly 2 is not able to import files with more than one visible shape (body e.g.). If you want to do this, try my A2plus workbench, it is installable via the addon manager. It works very similar to Assembly2.

If you import a file with more than one body, it is handled with A2plus as it would be one part. All bodies of the file move during constraining at once.

Within the assembly, you only can apply spreadsheet data to some values of constraints, e.g. the offset of planes or the angle of angularPlanesConstraint.

The rest you have to do within you source files for the assembly.

Thank you for your reply.
Can I get spreadsheet data from another FreeCAD file?

Thank you. I understand perfectly. Do you prefer to use Assembly 2 or A2Plus? Why?
I've seen a bit of each and I don't know which one is ideal for the future of my models.

Thanks
