In my work as an architect, I mostly use Sketchup to get a hold on the volumes. It's simply the best software for that purpose. Plans and elevations is done in Autocad Architecture (in my case).
For a while I've been watching this community to be updated on the use of Sketchup. And it's remarkeble what you can do, mostly very detailed work for rendering purpose.

But how do you use sketchup for architectural presentations?

Is it for clean renderings, for simple "2D" plans and elevations, perspektiv sketches, volumes for handsketching on tracingpaper or......?

I mostly use LightWave it provides 3D visualization, free cross-platform render nodes animation tools and much more.

I am trying to model cars in sketchup but it is hard, there is not any tool for drawing curves. I want some plug-in recommendations for this work.

This is a modern mass production highway-capable plug-in electric vehicles (PEVs), and also includes those plug-ins at an advanced stage of development or being tested in demonstration programs.
