Labelling/naming sketcher elements

[ishan_ae]

Hello,

I am using FreeCAD's Sketcher to create a 2D sketch. I want to extract the coordinates from this sketch and export them via a CSV file which, I will use for another application. The coordinates export part I have already figured out by playing around with Python APIs.

The 2D sketch is moderately complicated and I want to track the different elements(lines, splines, vertices) in it. I want to give these splines and edges specific names. This can then help me in identifying for which lines/splines the vertices have been exported.

Is this kind of naming possible in Sketcher ? I have looked into this but could not find any solution.

Thank you.

It's possible for dimensions: When editing a dimension there are two input fields. The upper is for the dimension, the lower is for a name.

Geometry elements have extended naming facility (just needs to be checked), is that not enough?

Thank you Chris, I will look into this.

Syres, I am not able to change the extended names that show in the GUI. I can only extract them. I guess they cannot be changed.

Do you mean the "extended information" shown in the elements list?

As the OP is using 0.19.x I was using the term used in that version, it's since changed sometime in the last couple of years.

Looking at that information, I don't think that it is stored somewhere. It just shows derived information: element number, construction/extended, source of extended, and in most recent versions on which layer the element is.

I think I will go element by element by clicking on it since there seems to be no way to label them.
I thought that the field "Extended naming" can be accessed and changed. Unfortunately, it can only be accessed.

There should be a way to add non element text fields to a sketch - and to put custom labels/references on elements including construction elements.

About the only thing one can do is to customize the name of the sketch.

There is a real need to create text for sketches - similar to the dimensions of lines - one should be able to label lines - and have a non element labels for sketches.

what's the use case for that?
