Hi everybody,

When I am pulling geometry off an imported solid model sometimes I have a surface or a line that will not read a radius with the dimension tool.

In a similar deal - sometimes I can not pick the mid point of profile curves - in the model or even after I bring them into a drawing.

I have got around it buy making another sketch and setting points eye ball close to the mid point - coincident to the line and then dimensioning to an end point until it is centered - with a missing radius I draw a circle - add coincident constraints to the end points, and change the circle diameter till I get close for a size.

When is a radius not a visible radius....?

What geometry lets you pick a midpoint & what will not let you...?

Thanks

Rich,

If SolidWorks converts the edge to a spline, then you cannot assign a radius to the curve. Click on the curve, and see what the PropertyManager calls it. It will create a spline instead of a radius of the curve is at an angle to the original curve, because the resultant projected curve is no longer a circle or an ellipse. If the angle is 90° to the plane of the original curve it will just convert to an ellipse, but if it is anything else, it has to convert it to a spline.

Your technique is similar to what I do, by using a 3-point arc overtop the curve is the same one I use to approximate it. The mid-point issue is the same problem, but I'm not sure of a great solution.
