Install The Add-Ins

Set up AltSkripts + FRC-COTS — the custom tools this course is built around

Est 13 minLevel BeginnerSoftware Fusion 360
01

Why Add-Ins?

Add-ins are Fusion's version of Onshape FeatureScripts — custom tools that automate the repetitive FRC moves.

  • They turn 10-click jobs into one dialog
  • Everyone on the team builds parts the same, correct way
  • We use two: AltSkripts (our toolbox) and FRC-COTS (parts library)

AltSkripts was written by Athan (7558), inspired by Team 4698's FRCTools and Team 5000's FRC-COTS. You don't need to understand the code — just install and use them.

02

Get The Files

  • Download AltSkripts and FRC-COTS from the team drive (ask a lead)
  • Each is a folder containing a .py file and a .manifest

Drop Them In The AddIns Folder

Fusion auto-loads add-ins from one specific folder.

  • Mac: ~/Library/Application Support/Autodesk/Autodesk Fusion 360/API/AddIns
  • Windows: %appdata%\Autodesk\Autodesk Fusion 360\API\AddIns
  • Put each add-in's folder inside AddIns
  • The folder name must match the .manifest (AltSkripts, FRC-COTS)

04

Enable Them In Fusion

  • Utilities tab → Add-Ins (Scripts and Add-Ins)
  • Open the Add-Ins tab → select AltSkripts → Run
  • Check 'Run on Startup' so it's always loaded
  • Repeat for FRC-COTS

Key idea

Install once. Use all season.

After 'Run on Startup', the tools live in your Sketch and Solid tabs every time you open Fusion.
