Eagle CAD Tricks

  • Move parts between sheets:
    • group part (even if its just one)
    • enter in the command line: move (> 0 0)
    • move to other sheet (e.g. sheet 2): edit .s2
  • Measure trace length / impendance: run length-freq-ri (original link) NOT needed in v6 for differential signals, use the differential routing tool instead


  1. Install Sketchup: http://sketchup.google.com
  2. Install EagleUp according to the instructions on its website: http://eagleup.wordpress.com
  3. Install FreeCAD (needed to create new 3D models): http://free-cad.sourceforge.net
  4. Install Meshlab (needed to create new 3D models): http://meshlab.sourceforge.net/

Creating new 3D Models

EagleUp uses Sketchup models of each part and combines them into a board model. The best way to create part models is to import 3D data from the part manufacturers and convert them to Sketchup (and color them there).

Step 1: Download Part

Step 2: Convert to STL

Start FreeCAD

  1. File → Open → Select the STEP (.step or .stp) file
  2. Mark the part (green highlighted)

Select File → Export and select the STL (.stl) mesh file format.

Step 3: Convert to Collada

Start Meshlab. Go to File → Open → Select the file and click 'Open'.

Export the file: Go to File → Save As → Collada (.dae). Leave all options default and save the .dae file.

Step 4: Import in Sketchup

File → Import → DAE

Step 5: Soften Edges and Color

Select the complete part, right-click on it: Soften / Smoothen Edges → Tick the “Smoothen Coplanar” checkbox
