Something more speedy and more easy for select only fillets for erase them in some cases!
Like on pyramid first post : https://moi3d.com/forum/index.php?webtag=MOI&msg=11803.1

- Select the Object
- Up Right Menu Details / Faces /Plan = n Faces --> Click "Faces"
- x Planar --> Click "Planar"
- Invert Selection

or even more speedy ! ;) You must have your object alone on the screen! So Select it Invert Selection / Hide)
- Browser "Types"
- Faces / Planar!!! (Right Click on "Planar" for select them )
- Invert Selection

then
Remove Fillets by
Shift + Del key
or Right Click + Shift
or Right Click on Del Button (red "x" Left bottom Bar)
Et voilà! :)

Does it possible to have a script for that ? For ultra speedy users that i am not... due bad memory ! :)
