You can construct an ellipse from the intersection of a non-parallel plane and cylinder.
To construct an intersect ellipse:
Open the Construct Ellipse dialog box (Insert | Feature | Constructed | Ellipse).
From the Method list, select the Intersect option.
From the Feature list, select the first feature; it can be either a cylinder or a plane.
From the Feature list, select the second feature.
If you selected a cylinder as the first feature, then this must be a plane.
If you selected a plane as the first feature, then this must be a cylinder.
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. PC-DMIS constructs the ellipse at the intersection of the two features. The constructed ellipse will have the plane's normal vector.
The Edit window command block for a sample ellipse would look something like this:
ID=FEAT/ELLIPSE,CARTESIAN,OUT,NO
THEO/X,Y,Z,I,J,K
ACTL/X,Y,Z,I,J,K
CONSTR/ELLIPSE,INT,feat1,feat2
