I would like to just draw a simple line on the z axis of my drawing. In Sketchup you do this by locking onto any axis of your choice, I can not figure out how to do this in VW. I have been reading a lot and found a way via 3D Polygon. Here I then struggle with entering the length accordingly and accurate. In the Screenshot you can seem three polygons on the layer. But I would prefer to just draw lines and then connect to create the surface. In my line of work I can not use double walls. So I have to basically draw 2d surfaces which can live on any axis.
Would be great if someone could help here.
