im in the process of creating a new workflow for my projects and am wondering if there is any way or add on to create new custom primitives other than drawing or apending them all the time?
you can write your own addon to add whatever primitive you want!
look at the add extra objects and other addon
there are already a lot of other primitives included !
You can write an add-on that will import meshes (like .objs) from the file system.
Do you have ADD Extra Object plugin activated ( Built in)…adds a bunch of primitives.
