Create a circle in a base sketch.

Note Do not create the circle as a whole, but rather as a quarter, which you compete to a circle by rotation. Background: In order to ensure compatibility to various CAD systems a minimum number of 4 sketch elements is required.

Quarter circle

Insert a Pattern origin .

Note The pattern origin has to be on a contour.

Pattern origin

Create a parallel reference plane with the desired distance and on it a new sketch.

On sketch 2, in the same way, create a circle again. (Here in the example it is smaller and shifted in relation to the first circle.)

Sketch 2 on parallel reference plane

Set a pattern origin again.

Note The pattern origin has to be on a contour.

Second pattern origin

Mark both sketches under History and then click on Create sweep base.

In the 3D History, select both sketches in the correct sequence (either with Ctrl or Shift key) and then click on Create sweep base or Create sweep cut.

Create sweep base

-> The dialog box History opens.

Dialog box "History"

Confirm with OK.

-> The sweep is displayed in the 3D view.

Sweep base

Precondition is that the "Sweep cut" is not the first feature. In this case an error message would appear.

Error! First feature can not be a cut!

So at first a basic body needs to be created.

Now the command Convert to cut can be used.

Convert to cut
