OT, but does anyone know of a vector drawing program that allows me draw in a similar that Fusion360 or SolidWorks does with their 2D CAD sketches?

It also needs to export to some standard format to be used for print, so using SolidWorks of Fusion360 isn't really an option, I can't export the vector 1-to-1 onto a pdf and do proper colors with those.

I cannot for the life of me figure out bezier curves to create arc sections with proper radii that blends into another line, and abusing adding and subtracting shapes from each other is a cumbersome process and editing the final shape often requires me to start all over creating that composite shape.

I would like to have more technical and fine-grained control over the way my drawings are made, than what pulling with my cursor on those handles gives me.

It's not exactly what you want but I have made a little software that is a sort of mix between Inkscape and Geogebra in which you can define a lots of shapes geometrically (https://www.ludigraphix.org, recent show HN : https://news.ycombinator.com/item?id=19942367)

I had some thoughts of writing some software a bit like that, and would be interested and hearing what would be the feature set for a minimal viable product. *

For example, if you could do things like

>I cannot for the life of me figure out bezier curves to create arc sections with proper radii that blends into another line, and abusing adding and subtracting shapes from each other is a cumbersome process and editing the final shape often requires me to start all over creating that composite shape.

and also

>I would like to have more technical and fine-grained control over the way my drawings are made, than what pulling with my cursor on those handles gives me.

But for everything else (color/fills etc.) you would export to other software

>It also needs to export to some standard format to be used for print, so using SolidWorks of Fusion360 isn't really an option, I can't export the vector 1-to-1 onto a pdf and do proper colors with those.

Would that still be a useful product?

* Disclaimer: Way back around 2001/2002, I worked on the Solidworks sketcher, and also before that used to work for D-Cubed Ltd. (SolidWorks and Autodesk Fusion 360 sketchers both implement their unbounded geometry constraints/dimensions using the D-Cubed DCM2 constraint management component licensed from Siemens PLM.) To implement what you want one needs at least some of the features from DCM2. Either implement one's own code, or one licenses from Siemens PLM (expensive) etc. Most licensees for DCM2 were 3D. There was one product that I recall that fits your description - Imagineer from Intergraph - but it got discontinued. I suspect that there is a market for what you describe, but maybe it's somewhat niche.

I would look into illustrator plugins. Namely VectorScribe, CAD tools and xtreampath all have different ways to draw vectors.
