Getting Started with SketchUp : Step 3: Draw your geometries

This guide will walk you through the basics of using SketchUp. Follow the steps in this guide to build and decorate a Library study room.

Draw Your Geometries

Step 3

Since you are drawing from an image, you’ll need to change the view of your drawing area so that you can see your lines. Changing your view to X-Ray (View > Face Style > X Ray) will let you see both the floor plan image and your lines.

Once you have the flat image placed in your model, you can use the line and shape tools to draw over the lines on your model. Make sure to keep your lines plumb with the axes so that your walls, windows, etc aren’t at weird angles.

To make your lines a specific length, click once to start the line and then enter the length of the line in inches (i.e., 11’1 -- you don’t need to include the inches symbol). Hit Enter and then you’ll have a line! Move around your outer walls to make a box

Make sure that your lines are connected. When you close a shape it will become slightly shaded.

Some tips when drawing your floorplan:

  • Use the Rectangle tool to create squares and rectangles
  • Use the Eraser tool to delete edges and combine rectangles into one shape

Help! I can't see the measurements box!

SketchUp has a box in the lower-right corner that displays measurements as you're drawing lines, using the tape measure tool, or many other tasks. When you are typing in the length for a line, it will appear in this box. If you open SketchUp and this box doesn't show up, you can open it.

  1. Open the Toolbars menu (View > Toolbars)
  2. Make sure the Measurements box is checked
  3. Click Close.

Turn your lines into walls. You need to add wall width to make your lines into walls. With the Offset tool (F), click on an edge of a wall and move your cursor towards the center of the image. Type in 5 and hit Enter to make your walls 5” thick.

  1. Turn off X-Ray mode, because you no longer need it. You can also delete your floor plan if you want. That’s up to you.
  2. Use the Orbit tool to rotate your model. It is easier to extrude vertically when you are looking at the model at an angle.
  3. Activate the Push/Pull tool and click on one of your walls. The walls of our study room are 9’ tall, so type in 9’ when the Push/Pull tool is activated to get walls that are exactly 9’.
  4. If your walls are tinted blue, you need to reverse the faces of your model. Basically, your room is inside out. Activate the Selection tool, then triple-click on your model to select all. Right-click and choose Reverse Faces. Now your room is outside out.
