Altium Designer setting design rule for distance between lines on mechanical layer

[mack369]

Hello,
I want to specify the minimum distance between lines on a mechanical layer. There is no problem to do that between signal layers but I couldn't find any rule for mechanical layers.

I need it because some components from my library have the outline on mechanical 15 layer and it would be handy to have a rule that doesn't allow to put them too close.

Have you specified the minimum components clearance in design rules and enabled online DRC check?

you can define clearance rule for the mechanical layers. open design rules then click clearance then click 'Layer' tick. Now you will see at the rigt region(full query) OnLayer().
ıf you write in the prantesis Mechanical 15 you can manage the clearance on the mechanical layers.

an example;
OnLayer('Mechanical 15')

regards.
