steven-g Posted January 15, 2018 Share Posted January 15, 2018 Basic geometry, the ellipse major and minor would be 0.7071 of the distance between the diagonals of the isometric (square). So copy the rhombus using its own center and scale one of them from the center by a factor of 0.7071 and then use the points of that to draw your ellipse.

basty Posted January 16, 2018 Author Share Posted January 16, 2018 Maybe one way ellipse Centre M2P pick the end points for the centre of ellipse then use Perp to pick the edge. What is M2P? Quote Link to comment Share on other sites More sharing options...
steven-g Posted January 16, 2018 Share Posted January 16, 2018 It's a "command modifier" when a command is active and is expecting you to select a point with the mouse, you can type m2p or mtp, and Autocad will then let you pick 2 points and it will work out a position halfway between those 2 points 'm2p' mid 2 points or midway between two points. It's worth looking in the help file for other command modifiers. Quote Link to comment Share on other sites More sharing options...
basty Posted January 16, 2018 Author Share Posted January 16, 2018 It seem few people here know about projection. Quote Link to comment Share on other sites More sharing options...
steven-g Posted January 16, 2018 Share Posted January 16, 2018 I don't know about the others but I'm old school (well old anyway), I learnt on the drawing board and you had to know how to construct certain types of geometry. Quote Link to comment Share on other sites More sharing options...
