No problem with the question - hey that is what the forum is for!
But I do have to keep some secrets Tyler ....
That is why I do the PUG training events - to let out all my secrets - Full Open Kimono .... (what a thought!)
Seriously - you create those as follows
1) In BC-HCE v4.12 or earlier you have to set your Menu Layout (Project - Set Menu Layout) Use Large Icons for Quick Access Toolbar to Yes (check box) Without Large Icons this doesnt work - in v5 next month it works anytime.
2) Once you have done that, in the Menu bar - Right Click and select Customize - it is at the base of the list
3) You can create New Toolbars - eg one for Edits, One for CAD Stuff (Move, Copy etc.), one for Surfaces and so on.As you do that it asks for the name and where you want to dock the toolbar (Right Side) - it then places a toolbar placeholder on the Right side of the screen.
4) Then step to the Commands Tab - You can pick a command group like Corridor - and then all the commands are listed on the Right side - find the command you want and drag and drop it to the Toolbar in the location where you want it. Repeat for the commands that you want and for the Toolbars you want.
You can turn Toolbars on and off as you need them, you can double stack them if you want to etc.
From the Options Tab - you can deselect "Large Icons on Toolbars and they will shrink in size so you can get more commands down the side
Tip - Muscle memory forces you to always go to the menus (because that is what you are used to doing. Take the commands out of the Menus (to make more space) and force yourself to use the Side toolbars. Within hours you will retrain yourself and your production will soar like an eagle.
Hope this helps - Happy productive modeling!
