Parametric updating of Drawing Dimensions

[ChemEngUser]

Hi Everyone,

I'm very new to both FreeCAD and python (I only just downloaded today, so please forgive my inexperience). My goal for using FreeCAD is to have a standard drawing of a pressure vessel that has its radius, length, and nozzles updated automatically from excel and exported as a SVG file so that it can be used in a vessel specification sheet.

Updating the drawing automatically using Python doesn't seem to be too big an issue; however, I found out that the Drawing workbench requires an add-into show dimensions on the 2D drawing. Unfortunately, this add-in appears to have the limitation that the the dimensions will not update if the constraint variables are changed in the drawing, which throws a wrench in my plan. (Link: https://www.freecadweb.org/wiki/Drawing ... ning_Addon)

Is there something that I am missing that would allow me to show dimensions in a 2D format that are able to get updated automatically via updating parameters in python?

Thanks in advance!

Hi and welcome to the forum!

Drawing+DrawingDimensioning is deprecated, they are no longer maintained. Use TechDraw workbench instead. You don't have to go via SVG to create a pdf for your documentation.

I think in the Addon manager the annotation should be added: "This addon is marked as obsolete"
This is done also with other workbenches as e.g. Assembly2

Excellent, thank you both very much, this is precisely what I needed.
