I see. It sounds as though if I use sketches, I can indeed easily modify just a portion of the wall. However it seems as though if I use draft lines, I have to replace the base wire.
I'm quite puzzled. Replacing the base wire is not a speedy operation. When doing architectural modeling, deleting a single wall, shift a single wall, split a single wall, or rotate a single wall is something we do all the time. Literally hundreds of times a day. Designs change and sometimes we have to experiment in 3D. Having to redraw and replace a base wire each time is not practical.
In Blender, it is easy to grab a portion of a mesh and cut it, move it, or rotate it. In Revit, I can trim, extend, rotate, move, delete, and join a portion of a wall. I have seen co-workers do similar in ArchiCAD.
In FreeCAD, I notice that although Sketcher WB allows for quick drawing and deleting single lines, it is missing tools like trim / extend and rotate. These tools are vital! It is also missing the ability for me to grab a single line and move it say 5000mm up the page.
With draft lines, I have this flexibility but only if I split each line segment into its own wall object. And once I do that, I do not get clean wall joins.
Can somebody please upload a brief video demonstrating how they rapidly create, move, rotate, join, and split walls? Perhaps that might clear things up and help me understand the intended workflow.
