If you want to copy an existing file and the drawing with a Brake View and change the length of the part, you have to change the position for the Brake View manualy for every copied file.
It would be nice, if their could be a Option, to fix the Position of a Brake View in the drawing and make the width variable in coex with the length.
eg:
Aluminium Profil is 500mm and have a extrusion 20mm from the top. Now we dont Need the length of 500m. Only 400mm would be enough for the drawing.
We create a Brake View at postion X.
Done.
Next we need the same type in different length.
Copy the File.
New length for the profile 1200mm.
The drawing have to change the length for the Brake View in adition to the length.
You get the same drawing with a new length in a vew seconds.
