SketchUp Tips and Tricks: Perspective vs. Parallel Projection

In Google SketchUp, you can model in either perspective mode or parallel projection. Both have their benefits. For instance if you need to model in a really narrow or enclosed space, you can adjust your field of view to a high number like sixty. If you are working with layers of information that you would like to align, turning on parallel projection can be handy. Here I will draw some geometries on a flat plane positioned precisely above my topography. Once that is done, I will use the drape sandbox tool to drape the lines onto this surface.

The nice thing about creating a "stamp" is that the geometries are created in a way that they can be moved after the stamp is placed. What you can do is just stamp the floor arbitrarily, then draw a geometry off to the side that you want the floor to snap to, then pre-select the floor and finally move it in the blue direction (hitting up or down arrow will lock it). Does that make sense? I will make a video about it, thanks for the idea!

why your skecthup has color pencils?

Hey Slug,

Good question. That is just a Mac thing, it is a part of how available system colors are presented.

Why Sketch Up 8 doesn't support Parallel Projection while rendering (in Vray).

The window shows Parallel Projection , but it still renders as perspective...I never had such problem in Sketch Up 7((((

Then I closed the holes/spaces by aplying some faces in the sides, it worked nicely, but was a lot of trouble, I thought sandbox would have more options to deal with the terrain, instead what I encounter is what I think to be one part of sketchup that is in the first steps of development.

But anyway, thanks for the answer, and please make a video or two about sandbox, because I think its not just me that have problems with terrain in sketchup :) Your help is much aprecciated tks!

Im sorry my friend, but I didn´t understand this concept :P

My solution was this, instead of creating a stamp for the terrain to receive the floor of my building (wich have a serious of complicated levels), I decided to use the drape tool. So, first I draw the outline of the building, then I used this outline face to drape the terrain, and then I could just erase the part that the building was going to fill.

o, I see, thanks man, one question about the sandbox tools if you can help me... I´m trying to use the Stamp tool, to raise the levels of a theater, but I can´t put on an exact meausre, and it won´t snap to any endppoints or so. Is there anyway I could stamp more accurately?
