Round filllet coordinate for pipeline
Round filllet coordinate for pipeline
(OP)
I have 3 known point, with coordinate P1-(X1, Y1, Z1), P2-(X2, Y2, Z2), P3-(X3, Y3, Z3).
straight line is draw from P1 to P2, P2 to P3. they are "not" colinear.
I would like to fit a round fillet to the conner with a "Known" radius of R, and I would like to know the coordinate of the 2 tangent point and the center of the fillet circle.
How can I calculated it in 3D coordinate with a sample single equation for each of the tangent point and center of the fillet, so I can use in Excel. Is this possible?

You do much easier in AutoCAD but you will be repeative or you could even simplify using a script file after you do the first set.

I understand that can be done in any cad package, but If I can find a way to do this in Excel. It will be greate as I do not need to go through the draft man each time i do small chane to my model.
I know some programing of VBA. but since I not touch the vector for 10 years now. can anyone help me the maths behind it pls.

and P3 as (X, Y, 0)
But how can I map back the coordinate please?
