I’ve inserted a txt file (point cloud data). It’s been moved and rotated. Where can I find the translation information (x, y, z, and rotation) ? Thank you.
Hello - the only way that I can think of is to insert the cloud as a block - then you can get at the transforrm info from a script.

Well it’s already moved. I could possibly reinsert a copy and move it to match. Then get the info as you’ve suggested. But with what script?
I’m using 5.0. We’ve just updated to 6.0, but I haven’t installed it and don’t have time tonight. I need this ready asap.
I think it is InstanceReferenceGeometry.Xform
. But you need to decompose it manually. It is the code in my component to retrieve the base point of a block.
if(blk is InstanceReferenceGeometry irg)
{
var trans = irg.Xform;
baseptr = new Point3d(trans.M03, trans.M13, trans.M23);
}
If you get a InstanceObject
instead, you may use InstanceObject.InstanceXform
and InsertionPoint
.
I would recommend to use a convex hull of the point cloud to match rotation and translation, as it is usually more recognizable.
