You can project an ellipse onto a plane. PC-DMIS projects the centroid of the given feature onto the plane, creating an ellipse. If there is only one input feature, the projection is to the current workplane. The major diameter of the projected ellipse is the width of the projected feature, or the probe's diameter (for feature without a defined width). The minor diameter is the length of the input feature, or of unit 1 (for features without a length defined).
To construct a projected ellipse:
Open the Construct Ellipse dialog box (Insert | Feature | Constructed | Ellipse).
From the Method list, select the Projection option.
From the Feature list, select a feature of any type.
You can also select a second feature. It must be a plane.
Select the In or Out option. For details, see the "In / Out Ellipse" topic in this documentation.
If you want to change the feature theoretical values, select the Feature theoreticals check box and type in the values. For details, see the "Specifying Feature Theoreticals" topic in the PC-DMIS Core documentation.
Click the Create button.
