hi could you please explain how you create ogee curve on a single line between two points

2. Is this what you are talking about? http://www.infodotinc.com/content/en.../14069_150.htm

HTH..............

3. I dont know the purpose of your ogee but I draw them often to use for
furniture moldings. Most classic molding profiles use ellipses rather than
radiuses. I devised a method of my own to draw them with Autocad.
First determine the overall length and the angle of the ogee.
Then draw a line at that length and at that angle on your screen.
Now draw a line from the bottom end point of your angled line at 35
degrees to your angled line to any point further than the top of your line.
Now using the "Offset" command "Through" option offset that line(the one
at 35 degrees to your first line) through the top end point of first line you drew. You now should have your meausured first line with a line from its
top endpoint going past it in the neg. Y at 35 deg. to it and a line from its bottom endpoint going past it in pos. Y at 35 deg. to it
Now draw a line from the top endpoint of your measured line to a point that crosses the 35 deg. line (the 35 deg line drawn in pos Y axis) and
make it intersect that line at 90 degrees.
Now offset that line "through" the other (lower) endpoint of your measured line.
Now if you trim off oll the overhanging lines you have a rectangle with your measured line inside it running from corner to corner.
Now using the "Ellipse" command draw an ellipse using the top righthand
corner of the rectangel as your first point, the bottom righthand corner of the rectangle as your second point and when prompted for a third point,
use "Snap To Midpoint" and snap to the midpoint of your measured line.
Now draw a second ellipse using the same method on the left side of
Now (usually I do this before I draw the ellipses) offset one of the rectangle ends (the short sides of the rectangle) through the midpoint of the measured line.
Lastly if select all the straight lines as cutting edges for the trim command and then trim away the correct parts of the ellipses you will
have an ellipticall ogee remaining.
Note: the 35 degrees used earlier is a guideline that produces a pleasing
ogee in most cases for me. Substituting a smaller angle will yield a less pronounced ogee a larger angle a more prounced ogee. Changing the angle does not affect the the rest of the procedure.
Also, I am sure it will work if you sustitute circles for ellipses.
Lastly, It sure takes a lot longer to explain without the aid of drawings
than it takes to execute Frank

Use a variety of arcs, circles, trim etc.

Bear in mind every ellipse has a major and minor radius/axis.
