Anyone able to provide a step by step guide to using double cut. I have followed several youtube videos but for somereason it doesnt work for me. Typical I make my own windows and doors then save them as components. Then create the double cut element and save its in the window component making sure the axis are the same. When follow the video exactly it doesnt work

Still no luck. I have tried running the repair as admin. No v2021 in right click contextual.
I tried deleting v2020 then running repair again. Still can not open a file creating in v2021
unless I open the v2021 first via the desktop icon/ shortcut and use "open file"

I can only open a file created in V2021 if I open the program first. If I right click on the v2021 file there is no option in the list to open with v2021. This is exactly the same problem I had with v2020.
The v2021 file I have created also has the older red SU icon no the new blue icon

I can open SU from the desktop shortcut. I create and save the file in the project folder but I can only open that file if I open SU from the desktop shortcut then choose the that file.
Yes I have tried reinstalling as admin. I am on subscription and have the most up to date version
This same thing happened with the 2020 version, I searched for a solution to the problem back then a luckily found a post someone had a file to download to correct this exact issue. Which they said was a bug with SU2020

If i try to open a file created in SU 2021 pro I get an error message
"this file was created in a newer version...."
I have to open SU 2021 then open file thru it What is the fix for this

I have reinstalled 2021 as Admin still no good

perfect thanks for this

Just got the book. So far it is impressive. Cant wait to do entire project with SU and LO

Sometimes I can get SU to exit out of a tool. I can hit the space bar and/ or the escape button several times to no avail. If I click on another tool sometimes that will do it. If I wait after hitting escape then the next time I hit it will exit.

I would also like to know more about Revit /SU workflow. I haven't adopted either to be my go to CAD program. Once Nick Sonder's book comes out I might go all SU

Ok, I get it, but to update a scene your saying not right click on scene tab, but use the update button in the scene manage is best.
