create a point on a curve, at a distance from another point

[boffin5]

Help! I have a curve, and on the curve is a point. I need to create another point at a certain distance from this point, but pro-e only seems to allow me to specify the distance from the end of the curve.

How do I specify it from an intermediate point?

I don't think you can do this in one feature, unless you specify both distances and then make a relation to control the location of the second point.

This can be easily solved with BMX.

How was the first point created?
You want a Real offset measured along the curve?

If the first point has a Real offset value you could simply pattern it.

If it's a Relative value or no value its a little more complicated but easy enough to do with an Datum Evaluate feature and relation. Creating a trimmed copy is much quicker and easier, though (taking all of about five seconds).

Boffin,

You can make a datum plane thru the point on curve (normal on the curve) and then you can create another point on the curve and with an offset from the plane.

or

You can split the curve at point, keeping both ends and then create a point on the desired curve segment using real distance from the original point used to split the curve.

Thanks Hora,

It sounds like splitting the curve is the way to go, as a planar offset would not give me a curvalinear distance along the curve.
