Hi Anis, sorry I'm not sure if I understand the question.

Do you want to know how to create a rectangle with rounded corners inside of MoI?

To do that, use the Draw curve/Rect command, and before picking the 2nd point of the rectangle, check the "Roudned corners" option, that will allow you to pick a point or type in a radius to get rounded corners.


You can also use Fillet to do that as well - if you have a plain regular rectangle, select it and then run Construct/Fillet. MoI will now show vertices at the sharp corners. The prompt will say "Select corners, or push done to do all" - here you can either pick a couple of vertices if you only want to do some, or press Done (or right-click in a viewport that is a shortcut for Done, also so is the Enter key) to do them all.

Then you will be able to pick a radius and all the corners of the rectangle will be filleted.

But I'm not sure if that was what you were asking about?
