Laser Cutter/Sketchup

[[File:300px-Sketchup-laser.png|thumb|right|300px|A 2D design in SketchUp]] ”Also shamelessly stolen from London Hackspace’s wiki”

[http://sketchup.google.com/ Google SketchUp] is a powerful, free, easy-to-use 3D CAD package by Google. It is normally used for producing 3D models many of which you’ll find on Google Earth. Its intuitive interface has me hooked, and I’ve created a fair few 3D models.

When I wanted to create designs for the laser I had a go with QCad but found the learning curve quite steep and was left frustrated. However, with a little research I found that it is entirely possible to use SketchUp in a 2D mode and export designs in laser cutter-compatible DXF format.

If you have any questions regarding SketchUp, I’ll do my best to answer them –[[User:Teabot|Teabot]]

*Can very easily progress from a 2D plan into a 3D model.

=== 2D mode ===

Watch the ‘[http://www.youtube.com/watch?v=F6eME_BiRFo Using Google SketchUp in 2D mode]’ video and/or:

*Select a millimeter template either on start-up or in ”Preferences/Template”
*Select: ”Camera/Parallel Projection”
*Select: ”Camera/Standard Views/Top”
*Optionally save this as a template for future laser cutter designs: ”File/Save as template”

=== Exporting ===

Make sure that you have installed the [http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl DXF export plug-in].

    If you have access to SketchUp Pro, you don’t need to download the converting software, you can export a DXF from SketchUp. Just make sure you do all the steps above about 2D Mode!
