Not environment-specific

Step 1 : - Create a construction circle using draw construction circle command. Choose radius of circle as required. (This circle may be inner circle or outer circle for our required profile)

Step 2 : Now we are going to create a polybeam using polybeam command and we are going to pick 3 points as marked below for creating polybeam. So that it covers 90 degrees.
First point is on intersection of horizontal grid and circle, second point is any intermediate point on circle and 3rd point is on intersection of another grid and circle as shown below.
And press middle mouse button to create polybeam.

Step 3: - Now created polybeam will look like made of 2 segments as shown below, we are going to make it smooth curve using chamfer option of Tekla.

Double click intermediate point of profile as highlighted above. This will open chamfer properties for center point. And we are going to select full curve chamfer.

And click on modify. To get smooth curve.

Now you can change profile of it as required. And also position how you want it to be aligned. (Above/Below) (inside/outside) etc.

Now we can copy rotate it to create 3 copies at 90 degrees to get complete sweep.

And finally we can create a cast unit using create cast unit command by selecting all 4 parts and right click and select Cast Unit --> Create Cast Unit.

Similarly you can create 2 parts of 180 degrees or 3 parts of 120 degrees to achieve full 360 degree sweeps.
