Hi all. I have a set of line segments and a set of surfaces. I want to find surfaces that intersect those lines. How may I achieve that? Is it possible using TCL coding?

Regards,

Rachit

    Hi Rachit,

    I would investigate using the HM TCL command hm_getclosestpointsbetweenlinesurface.

    It takes as input a line ID and surface ID.  If the line intersects the surface, it will return the intersection point(s) as a list of values in groups of 6.  If it does not intersect, it will return the closest point on the line and the closest point on the surface as well as the length (7 values).  You can refer the documentation for more info.

    Thanks,

    Rob H.
