Trimble SketchUp is a free 3D modeler.
When creating your models for 3D printing your file needs to be one continuous, solid object. The printer must be able to clearly distinguish between the inside and outside of the object it is printing. There cannot be holes or gaps in the model. There are tools that can help identify an close holes and gaps, but the majority of these areas should be found and closed within the original CAD model for best results.
STL FilesIn order to print your sketchup models, you'll have to convert your files to stl or obj files.
SketchUp Make allows you to export your models as obj files without adding any extensions from the warehouse:
But, if you would like an stl file rather than an obj file:
- visit the extension warehouse:
Sign in with your google account:
- Click Accept
Search for stl
Select the SketchUp STL extension:
Click on Install
When you are ready to export:
- Select your model
- Select File>Export STL
- Select the attributes that you would like your file to have and then press OK
Use this tool when you want to select part of your project - a line, a wall, a box, etc. If you select a line or wall with this tool then you can hit delete on your keyboard to erase your selection.
This tool is not for moving things around! Use the move/copy tool if you need to move things around.
Use this tool to create 3D text. Click on the tool, fill in the options in the box that pops up, and then click on your project where you want to place the text.
You use this tool to draw arcs (curves). Click where you want to start the arc, then click where you want to end the arc. Move your mouse around to adjust to curve, and when you have it the way you want it, click again to complete the arc.
When pulling out the radius, be aware of the inference directions. It is easy to pull in the wrong direction.
You can type in the exact radius.
If you are pulling the radius out, SketchUp will indicate when you are a perfect half circle.
To create an arc that is tangent to two sides, click a point on one side, drag along the other side until the line turns magenta, then drag the radius until that turns magenta
You can also draw arcs in sequence. Start the next arc from the endpoint of the previous arc, as you pull away when the arc is blue it is tangent to the last arc.
Arcs are made up of 12 segments (default). You can change the number of segments by typing a number followed by s while dragging the radius.
Use this tool to reposition the location of your axes.
You use the circle tool to draw flat circles. You draw a circle by clicking and dragging outwards. You can specify the radius, by clicking, dragging and typing the the dimension of the radius, like 100mm, and then pressing the Enter key.
You can use the Circle Tool to draw a polygon. To make the circle a polygon, click and drag, then type the number of sides followed by s (5s) and hit the Enter key. The default number of sides of a circle is 24. When you extrude the shape drawn with the Circle tool, you will get a smooth cylinder:
When drawing another circle, you can reference the center of the first circle by hovering over the edges for a moment and then moving your cursor near the center. SketchUp will snap to the center point.
To get information on your circle or polygon, select the shape then CTRL+click and select Entity Info.
