Moving a block that has associated visible text attributes.

[Anonymous]

Ok, I am more than sure I am missing something simple.

I am using managed classes to insert multiple block references into modelspace. I wish to insert a block and then move it (change its Position) which I can do. The problem is that my attributes associated with this block reference do not move.

Could someone please point me at the correct function(s)?

Well, it seems I may have posted too soon.

I moved the block reference THEN updated the attribute reference and all is well (so far).

IF you move the block reference using a transformation matrix, THEN it should move all the attribute references as well. TransformBy should be used for move and rotate all the time.

Example:

Dim point As Point3d = AbsoluteLocation
Dim matM As New Matrix3d
Dim pStart As Point3d = brLabel.Position
Dim vDiff As New Vector3d(point.X - pStart.X, point.Y - pStart.Y, point.Z - pStart.Z)
matM = Matrix3d.Displacement(vDiff)
brLabel.TransformBy(matM)


Also there are more advanced ways to do point/vector math built into the point and vector objects.

Ah-ha! Thank you for the guidance.

Interesting.

Now when I use a function with TransformBy() the blockreference I insert does not seem to be present! It doesn't make it into the block def table as it did before (as such does not appear in modelspace, paperspace or anywhere). ....

Strange indeed. Can you post that code here? There are several posibilities, but seeing your code will narrow them down.

Hello askrius.

Maybe too lat but

I am having this problem as well. I don't know how to fix it and what do you mean by updating attributes.
