draw beam error

[chstech]

Here is a good one, Draw your lights, focus them, turn beams on, go to any 3d view, and someone please tell me why is the point source of the beam at the C-Clamp and not at lets say the front of the lens ?????

How do you fix that one!!

Drew,

When I do it the source appears to be at back of the instrument, which is where the lamp is, and near the clamp. So maybe that is why it looks like it is coming from the clamp

Are you sure? I just did it again using the ETC SptLt fixtures. For me it is coming from the loci at the c-clamp.

Let me clarify. It is actually the 0/0 origin in the 3d component of the symbol. Also where it would get it's Z Height reference from.

Drew,

That would make sense. To calculate the beam and intensity it needs the origin of the light source to be at the z as well a x & y coordinates.

It is wierd that the source is at the clamp, except that it is where you usually determine hanging height, but it isn't noticeable unless you zoom in on the intrument - I had never noticed until you brought it up.

I side hung a VL3000 on a truss and since the zero point is at the center of the base the truss tube was in the middle of my beam and blocked most of it. I changed the symbol's zero point to be in the middle of the yoke to fix, but what a pain to move all my fixtures over. Can't we have a edit location for the light source?

Jim,

For me it is noticeable in an ISO view.
