Adding points to model through SolidWorks Livelink

Hi,
I've got a rather complex geometry that I'd like to add a probe point to.
I'm importing the geometry through the SolidWorks Livelink.
When I try to manually drop down a point in COMSOL I get a geometry decomposition error.
That's weird, but what I'd really like to be able to do, is place my points in SolidWorks and import them into COMSOL through the Livelink.
However, I can't get this to work. I've tried selecting the "Curves and points" checkbox from the Objects to Import list, but even that doesn't work.
Any hints would be greatly appreciated. Thanks.
Scott

Hi
today in the current version you cannot add a single point to the middle of a surface in 3D as a point has to belong to a domain or boundary interface (at least that is my experience). So to put a "hard point" on a geoemtry I make it as the intersection of two lines either as intersection of two boundaries in 2D or cuting a boundary in 3D. if the point is in the mddle of a domain in 3D I create 3 planes that intersect at the point.
These additional internal boundaries do not really make the model much heavier, and are often useful to make your mesh more symmetric.
If the point is only used for postprocessing, you can define a point from a solution and have COMSOL intepolate all variables onto that point, in thii cas the point might be arbitrary inside any domaine or on any boundary, without having to have adjacent lines/faces

Good luck
