For a horizontal ellipse, that axis is parallel to the [latex]x[/latex]-axis. Ellipse. The minor axis of the ellipse is the shortest width across it. Offset your ellipse and draw a line / RP from the intersection perpendicular to the offset ellipse. When you draw in Revit, temporary dimensions are created on the fly to determine positions and distances. Now place aligned dimension. 3. You you need to LOCATE the dimension line itself. Add dimensions to reference planes. I don't have video recording software installed at work, so best I can to is type it out Ellipse Draws an ellipse from a primary and secondary axis (Walls, Sketches, Model and Detail Lines only). Regarding dimensioning: Arc Length dimensions do not work with elliptical forms. This allows you to change the radii proportionally. If you created an ellipse for a sketch-based element, click the edit option to enter sketch mode. This panel is available in Architecture, Structure, and Systems tab. Fot the ellipse dimensions set the properties (with Ctrl+1, or preset a dimension style) so that only the second dimension arrow is displayed and no extension lines are used.
