How do you create a round (radius) along part of an edge

[andrewsepha]

Hi, we are trying to create a radius on an edge, but want it to stop half-way along it.

We can think up long-winded ways of doing it, but someone may know an easy method and make us look silly!!??

Thanks in advance for your response

Andrew.

One of these should do the trick.

draw a curve of the radius you want and use the technique in this post. That is the easiest/powerful way to do it in cad.

Another way is by creating 2 points along the edge that are very close together, then use a variable radius round.
To create the points you can use the plane normal to curve along the edge to be rounded (or any other reference plane or surface), then create intersection points between the planes and the edge.
Now when you add the variable radius round you can specify the rad at these points. eg 10 at start of edge, 10 at next point, then 0 for next point and end of edge.
This method might not be as exact because even with the points very close together you still have a transition from full rad to zero rad, but it should be a bit more flexible, especially for curved edges.
