Once floor mass is combined with curbs...etc and then sloping is added, there is no way to edit the grade beams without resetting the slab to flat which then must be reworking to the needed slope. This leaves us with many thin unerasable lines in the section cut representing the boundary of each mass unerasable.
Need a solution as to either be able to
1-Erase these lines byway of Linework command "currently did not work on such lines when tried to change to invisible lines."
2-Be able to apply an override to see through rebar detailing over the masked region that hide these boundary lines
1st option would be a better implementation.
