Which software do you use/can you recommend for planning?

I have read them all - but I didn't quite find what I was looking for with the suggestions - maybe someone still has a tip.

I need a program ONLY for the exterior view because I am still unsure about the window size, I cannot accept downloads and I don't have Java on my computer either. I thought maybe there is such a program also with certain window manufacturers?!?

Do you have a tip for me?

To my knowledge, at none. But I do not know for sure more than the late Günter Schabowski.

can recommend cadvilla. I also did my electrical planning with it and then also drew sockets and switches in 3D. I import many models from 3dwarehouse, for example, there are many Ikea furniture pieces available.
