Positioning problems

I'm having real trouble positioning my objects consistantly.

I'm creating a pivot and positioning the mesh so that the pivot is in the centre of the mesh, and then positioning the object at 0,0,0

This works for one mesh, but another one is way out for some reason.

playArea[index].pivot=CreatePivot()
playArea[index].mesh=CopyMesh(loadData[6].mesh,playArea[index].pivot)
PositionEntity playArea[index].mesh,0.0-(MeshWidth(playArea[index].mesh)/2.0),0.0-(MeshHeight(playArea[index].mesh)/2.0),0.0-(MeshDepth(playArea[index].mesh)/2.0)

and this for creating the initial positions

s.pivot=CreatePivot()
s.mesh=CopyMesh(loadData[7].mesh,s.pivot)
PositionEntity s.mesh,0.0-(MeshWidth(s.mesh)/2.0),0.0-(MeshHeight(s.mesh)/2.0),0.0-(MeshDepth(s.mesh)/2.0)

and this for displaying them :

PositionEntity playArea[index].pivot,0.0,0.0,0.0 
PositionEntity s.pivot,0.0,0.0,0.0

The problem may be that you're not taking into account the mesh's minimum x/y/z.

Try doing:

s.mesh.min_x+(s.mesh.MeshWidth()/2.0)

...and similar for all the lines above. min_x/min_y/min_z store the position of the left-most, bottom-most, near-most vertex.

Generally though, I'd advise against using MeshWidth/Height etc. I'm sure there is probably an easier way to do what you're doing just using the standard Entity commands.

Would be nice if there was a command to auto-centre an object - I'm just so used to it being done automatically (ala DBPro), and its very handy.

I'm trying various permutations, but so far its got somewhat close, but not exactly how it should be - for some reason it seems to be a few units out in all directions.

FitMesh will centre a mesh - for example do:

FitMesh mesh,-10,-10,-10,20,20,20,True

I presume that will work for loaded objects too, as well?

Looks like its sorted now.
