Midpoint of edge tangent to circle

Henk_de_Vlaam

The plane of a plate is tangent to a cylinder (red circle).
To get it symmetrically touching the cilinder I also like to fasten the midpoint of the plate's edge (red arrowed mate connector) to the green arrowed circular edge. 
How do I get this?

variable should work as MC offset input in part studio only. if these parts are designed in place in the same part studio, you can attach a mate connector of the plate part directly. if they originate from different part studios you can derive the cylinder part to the plate part studio, measure the cylinder diameter with Measure value FS and use it for offseting mate connector

the mate connector of the plate should have an offset in the direction of plate normal equal to of the cylinder radius. then it will be tangent when mating to the mate connector in the center of the cylinder edge

@konstantin_shiriazdanov thank you, that is a trick.

However, this constraint is only valid with a fixed cilinder dimension. In this case the cilinder dimension is configured, so the diameter is variable.
What I'm looking for is a constraint that works with different cilinder diameters.
Any other idea?

Use of a variable could be a solution but the lack of global variables is a pitty. Furthermore, in this case that would not bring the solution because I found that variables can only be used in dimensions and unfortunately not as driving value for a mate connector offset and pattern instance count value.

@konstantin_shiriazdanov,

1. I found why the configuration variable did not work beside dimensions: I used the (variable) Name instead of the Internal FeatureScript ID (the configuration variable in parentheses).
2. Because the plate and the cilinder are designed in the same PS I used your suggested MC in that PS. Now everything is fine.

Thank you.
