This video demonstrates the two primary methods of using polar arrays in FreeCAD.
I attempt to point out how much faster the Draft Array is at completing a similar task.
It shows the same part being created in Part Design Workbench and then using the Draft Array tool.

![OpenSCAD - Project Enclosure - Part 3 - Fillet Mounts
In the 3rd installment of this Tutorial I show one way of adding mounting posts for the Arduino UNO. In the video I show how to create filleted posts at the correct positions for an UNO
This video demonstrates a number of features of OpenSCAD:
Fillet:
- rotate_extrude()
- 2d Shapes
- intersection()
Vector Variable
Vector addition
Using text() to identify objects.
The video ended up being a bit long. Sorry about that. I should have broken it into two or three.
I made an error when measuring post number 4. I measured the circle of the push-button instead of the hole ( see comments ). The correct value for Post4 should be corrected as follows:
//post4=[ 6.35,49.53,0];
post4=[15.24,50.8,0];
Sorry for any inconvenience.
The Arduino Model I used to get measurements can be found at: http://www.thingiverse.com/thing:253463
Also, in the comments it was mentioned that there are many diagrams available with measurements. Use googles image search with arduino diagram and you will get many results. I used FreeCAD to measure the model as I thought it would be usefull in other cases. It also means I can get measurements exactly as I need them. Provided I measure the right thing :) OpenSCAD - Project Enclosure - Part 3 - Fillet Mounts](https://i.ytimg.com/vi/xwHybCZK-6k/mqdefault.jpg)
