entity type button grayed out

[kendo]

why is this?
from the "input" toolbar, the button stays grayed out, is there something I have to do first?
Wether I'm in design mode or manufacture, its no use

by the way,
I'm trying to put a point at the center of all arcs of certain radius,
but I'm stumped at the first step
I don't need full blown solid machinist license to do something this simple do I?

I got entry milling version 12.5 if it helps
thanks in advance
Kenny

no help eh?

I'm guessing that selecting entities parametrically requires a license upgrade then.

Hello Kenny,
You need to have a command active that requires input, such as creating a line or an arc or using the delete command.

For points at the center of arcs, in the menu click Geometry > Point, check the box that says 'Arc Centre', then window select all of your arcs. A freeware utility called 'Group Holes by Diameter' will handle this a lot better.

Thanks Kenny,
