There is no longer a command in 18.1 to project cross-section construction lines to a workplane. The only option is to project cross-section geometry to a workplane. Am I missing something or is it really gone?
in v17 or earlier you had the choice between geometry or construction lines and then make the cross-section.
In 18.1 i didn't yet find a button to make the choice.
The commands to switch are
If you push the button cross-section followed by GEOMETRY_MODE :CONSTRUCTION in the command line ENTER
the cross-section will be made of construction lines on the workplane.
If you need this often, you can create a button.
The exemple create the cross-section made of construction lines from the preselected part.
i had a look for other commands.
If you draw a rectangle or a circle you can make a right klick and this opens an command dependent menu where you can make the choice between geometry or construction lines.
So i created two new buttons one with
GEOMETRY_MODE :REAL the other with
Those buttons i placed in the right klick window menu.
Now i have the same behavior for all commands.
Command, right klick in the window, make choice and execution.
