My way into CAD software was 1. Dealing with DXF editors like QCAD. 2. Trying to tackle parametric CAD, I ran Onshape’s tutorials, they have pretty good technique tutorials, like how to draft a paperclip, that are applicable to most parametric CAD packages. Then learning how FreeCAD’s spreadsheet works.
FreeCAD has a full-on spreadsheet built in, now it’s feature poor compared to Excel or LOCalc but you can store and calculate dimensions there and then use them in the main drawing. Other software has features that accomplish this but it’s not as flexible and familiar as a spreadsheet. FreeCAD has some usability issues but everything else out there is either drawbackware or subscription.
I’ll warn you now it can get a little tedious, because you refer to the data in a spreadsheet like referencing variables in a Python script. In most fields you can type in a dimension, you can click a formula button or hit the = key and then type in a formula. Or you can reference a cell in a spreadsheet. that might look like “=spreadsheet.A4” for the contents of cell A4.
That isn’t very readable and I don’t trust it not to break if you add rows or columns or whatever, so there’s an Alias function. You can give each individual cell a name. Which is slow and tedious. In the Addon Manager you’ll find some macros, one called EasyAlias which, select a cell, click the EasyAlias button, and the cell to the right of your selected cell gets the contents of the selected cell as an alias. In other words, if Column B is a bunch of labels and column C is the actual data, highlighting B2-B17 and clicking the EasyAlias button will automatically alias C2-C17. That feature should be built-in. There’s also a macro for clicking a dimension, clicking a sketch feature, and then semi-automatically applying a dimension. It’s slightly temperamental but it works faster than typing “Dimensions.notch_height” over and over.
This is me with all CAD software 😭
I started with FreeCAD. Never changed 😉

Something new to learn for me. Didn’t know FreeCAD had that.

That’s very helpful, thanks
