How To Create Sketchup Topography

Creating a topographic map can be a huge pain in the neck. If you’ve ever tried to get GIS data or find a city topographic map you know exactly what I mean.  In this sketchup tutorial you’ll learn how to create sketchup topography quickly and easily.

How to Create Sketchup Topography

First you’ll need to import your google map into your project.

Make sure that your terrain is toggled on.



Next create a grouped rectangle that covers the entire site. Copy that rectangle up at your desired increment.
Pro Tip: Use an asterisk ‘ * ‘ and a number to multiply that number of copies at the increment you decided.

After you’ve copied all of your rectangles up, group them together.

Move your grouped rectangles off to the side (or hide them) so you can see your imported google earth terrain.  Unlock and explode the imported terrain.


Move your grouped rectangles (slicing planes), over your terrain again (or unhide).

Press Ctrl+A to select all, R-click on one of your groups.  Scroll down to Intersect Faces, and select With Selection.


Hide or delete your slicing planes Now you have a topographic map!

If you want to get rid of the faces, right click on one and select ‘all with same material’.


Sketchup will select all of the faces of your topography map. Hit delete and you’re golden!

Creating Flat Sketchup Topography

If you’d like to have a flat topographic map, create an additional rectangular surface underneath your lines.  This surface should be the same size as your map.  I use scale to get it exact.

Move your new surface below the topo line-work.

Select your linework.  Use sketchup’s sandbox drape tool.  Select your rectangular surface.


Now you have a 2d topo map!

    You aced the exam because at no point in your life has your brain been deprived of oxygen for 10 plus minutes. Seriously. That’s about the only way to fail.
    I took mine last year and after all the reading online I was scared. I bought practice tests, books, did hours of reading and studying.

    All this mess about the questions have several answers is a lie. EVERY SINGLE ONE of my questions had 1 answer. I rocked through the test in less than 20 minutes. I do have building/construction experience, but I remember the quality of the questions. Anyone using basic common sense and process of elimination can figure them out. I thought myself surely I’m not the lucky one who got the easy test? Nope, that’s just how the test is. But the internet likes to scare you, because they know you will buy study material.

    LEED has gotten a bad rap, and the deeper I get into green and natural building the more the joke of LEED is seen. Don’t waste your money or time on their “Green Associate” garbage and certainly don’t waste MORE money to keep up this phony “credential”

    Hi Tony,

    I need to take 5.0 PPD & PDD. Do you plan on posting notes such as “Caroline’s Notes” that you had posted for the various 4.0 exams for either of those sections? I found those notes to be some of the best resources in studying for the 4.0 sections. If so any idea when? Thanks

    Great post, very helpful with the lists of suggested materials, I just passed CDs in July and am taking PPP in November so I definitely needed the list.
