Help with this Bezier profile drawing.
-
If you just want to have the basics for a Classic Bezier.
Single click start and end position
Single click control points starting need the beginning
Double click to place last control point
While control points are active type the number of segments and an s, in this case I typed 48s, and hit enter
Click and drag the control points to shape the curve
Double click to add or remove control points
Click off the the controls to complete
Use the Edit icon on the toolbar if you wish to go back to edit mode.

Great, I get it. Thanks Box.

I'm not sure what those red and blue points are. But I don't think they are bezier related.
They are the focal points of two different ellipses.
The green and the purple are the center of two arcs. -

It's actually simpler than it looks (and I'm really bad at math).
An ellipse is actually the collection of the points that are found were the sum of theyr distance from focal points is the same.
It may sound even more complicated in this way, but that's actually how you can easyly draw an ellipse in real world (a bezier spline would be actually quite a bit more complex to replicate with a pencil, a simple string and a couple of nails).
Look at this. -
Damn! Something was niggling me about those lines and points... ellipse major minors of course... I have used Ellipses in my work for years. And always with the major/minor stick method.
Thanks Panixia. -

Thanks Panixia.Sometimes actually "less is more"

Panixia, Can you tell me the name of the Plugin you are using for this? I have always only scaled circles to produce ellipses til now. Thanks.

It's called "Tools on surface" and it's part of the Fredo bundle.
I strongly reccomend to buy the bundle because every single plugin in that collection is absolutely a banger. (Pay attention to the fact that you also need the free libfredo6 shared library to make those plugins work).http://sketchucation.com/forums/viewtopic.php?p=76625#p76625

Yep. I also paid for the package and they are solid workman's tools I could not do without and saved me a lot of time and extra effort.
