But you can quote your part in the 3D and get that rating. Once you have made this dimension and used it, you can hide it by going to display==>show/hide and then I don't know anymore. I'm not in front of my PC...
I understood for the block, but according to your image there is an extension on the block and this extension you can dimension it in the 3D and use this dimension...
I'm afraid I won't understand everything well.... because I really can't keep up with it in 3D :-(
If by extension, you are talking about a boss, yes indeed there is a boss function, but it's rather the length and width that I'm trying to recover.
And I also can't convert the entities without breaking the block.... or without creating a second sketch on the same plane as the block, which doubles the work
Once you have left your boss, you just have to use the dimension tool and then create your dimension. When you go to use the tool, it will have a choice to make with 4 options and it seems that this is the last one to select.
