How to Make Stairs in Google SketchUp 8 Using a Copied Profile
When building a model in Google SketchUp, making a staircase using a copied profile relies on using Push/Pull to create a 3D form from a 2D face. In a nutshell, draw the profile — the side view, sort of — of a single step and then copy as many steps as you need, create a single face, and extrude the whole thing into shape. The first time you do this is breathtakingly satisfying.
Follow these steps to make a staircase using the Copied Profile method:
Start with a large, vertical face; make sure that it’s big enough for the flight of stairs you want to build.
In the bottom corner of the face, draw the profile of a single step.
Select all the edges that make up your step profile.
You can hold down the Shift key while clicking with the Select tool to add multiple objects to your selection.
Make a copy of your step profile and place it above your first one.
Type the number of steps you want to make, type x, and then press Enter.
For example, if you wanted ten steps, you’d type 10x.
If you need to, draw an edge to make sure that all your step profiles are part of a single face.
Push/pull the staircase face out to be the width you need it to be.
