Hi Jerico, hi folks.
Normally, with SketchUp (SU), you model everything in real size.
If a building is 100 meters tall, you model it using this height.
Zoom out to be able to see the whole building and zoom in to see details.
With a large and detailed model, I often create two scenes, one that I call Workand the other Render.
In the Work scene, I set the rendering parameter to the bare minimum, just to show enough of the model to be able to work on it. For example, I use no shadows, no profiles, no fancy edges renderind, shaded mode instead of shaded with texture (in some extreme cases I may use monochrome or hidden line or even wireframe) and I also put as much objcts as possible on hidden layers.
In the Render scenes, I set all parameters to get the best result.
For each scene, I tell SU not to memorize the camera position so that I don't lose a carefully obited, panned and zoomed view.
Once that is done, all I have to do is to click on the Work scene tabto have a model that is light on the video card and that allows me to fluidly pan, orbit and zoom to add and/or modify objects. I just click on the other scene tab to see the model in full glory. Of course, I may have to wait a little for SU to render the view.
Just ideas.
