How should I create an arbitrary 3D geometry object with contour coordinates

Since there is no more function like ' loft ' in 3.5a, how can I create a 3D geometry object with only the contour coordinates with only 4.2 functions? Can I convert a set of parallel polygons to a 3D geometry, by assigning each one with a z-axis height and combining all of them? Thank you all!

Hello Yun,
These days, the lofting capability is available without any programming necessary, see www.comsol.com/design-module

Hi Jeff,

I would like to generate 3D CAD from multiple layers MRI images in Comsol. I am using coordinates manually and then export to in to Comsol. While I did that I can not make lofting , I think , because images coordinates vary (x and y value vary). I have two questions
Firstly, Is there any simple way to have MRI images coordinates in Matlab?
Secondly, Do you have any recommendations about lofting problem as mentioned?
Any rec commendations would be appreciated. Many Thanks in advance

Best Regards

Hi Enver,
Perhaps the function mphimage2geom that comes with LiveLink for MATLAB could be of some help. It can be used to convert images into geometry, will output either interpolation curves or polygons.
