Create an equidistant profile
1. Click Modeling and then, in the Draw group, click Equidistance. The Equidistance dialog box opens.
2. Set the tracing options:
Geom to select or ignore geometry.
Cons to select or ignore construction geometry.
Inters to stop at or ignore intersection points.
3. Click the start position on an element. The 2D CoPilot helps you find an intersection point, a midpoint or a point at a specific distance from an end point of the element.
4. If there are more than one possible directions to create a profile, click a second element in the desired direction. The profile is highlighted and a 3D CoPilot appears at the beginning of the profile. A blue highlighted point indicates the end of the profile.
5. If necessary, click on more elements to refine the selection.
6. If you click the wrong geometry element, click Back in the Equidistance dialog box to return to the previous selection. You can also click the highlighted point at the end of the profile or press Z to return to the previous selection.
7. Drag the 3D CoPilot to any side of the profile. When you drag the 3D CoPilot to a distance, the resulting equidistance profile is visible. The value in the Distance field in the Equidistance dialog box is positive or negative if you drag the 3D CoPilot to one or the other side of the profile respectively. You can use one of the following methods to define the distance of the equidistance profile:
While dragging the 3D CoPilot, type the desired distance in the quick-edit field. A positive value refines the distance on the current profile side. A negative value flips the side.
Directly type or edit the distance in the Distance field in the Equidistance dialog box. Type + or - before the value to indicate one or the other side of the profile.
8. At any time, you can also select additional elements to define the profile. Creo Elements/Direct Modeling dynamically updates the proposed equidistance profile.
9. Click New Param to complete the current equidistant profile and change the distance to draw other equidistant profiles. New Param helps you to draw several equidistant profiles at different distances from the original profile.
10. Click OK to complete the operation.

Using an equidistance that is greater than the smallest radius on the profile may produce unexpected results. Although such results are mathematically correct, they may not be very useful as they are drawn. You may need to insert fillets at the intersection points and delete the inner loops.

You can switch between Geometry and Construction modes while creating the profile by selecting either Geometry or Construction in the Equidistance dialog box.
