HI everyone,
I have a certain set of points i cartisian plane (x,y,z) and I need to generate a surface, say a Bezier surface, through these points. How can I do this with AutoCAD or Inventor. I am currently using AutoCAD 2014 and Inventor 2014
Thanks

Attach your dwg file here
and your ipt file over here

Dear Mather
I have no file as such. I have got 2 problems to be addressed as of now:
1. Placing the points in cartisian plane (x, y, z). Say I have 5 points (0 0 0), (1 2 3), (5 -2 6), (4 -8 -2), (3 9 1), now how can I insert them in my work space. (I only get options for inserting in 2D plane). As of now I am first inserting the points in 2d plane, say if i have to plot point (5, -2, 3) then first I enter point (5, -2) using 'PO' command and then I move this point 3 space up in +ve Z direction using 'MOVE' command. But since I have lot of points to be placed it will be hectic to use this method. And my other problem is that...
2. And once I got success in inserting them, then how can I make a surface passing through these points.
Thanks

How much experience/training do you have?
You should be able to enter points in 3D space without having to move them.
The 3DMesh command might be what you need. (but 5 points wouldn't make logical sense)

This is the attached file (working points.dwg) containg a set of data points. I need to make a surface as depected in other file (surface contour.dwg). To build the contour I have used spline.
Thanks
If you want to create contours without using C3D, InRoads or something similar then you'll need to manually interpolate them.
Draw lines from 1 point to the nearest point. Keep doing that until every point is connected to two other points. This will form triangles. Now at every place were a line crosses through elevation 100, you draw a 100 contour. Every location where your a line crosses elevation 110, you draw a 110 contour etc etc.
The more points (and break lines if you have them) the more accurate this will be. Doing it manually will be a tedious task -- ESPECIALLY if there are a lot of points.
