Using GeometricExtents with UCS problems

Anonymous — Mon, 31 Mar 2014 20:00:12 GMT

I've looked around at some other posts but can't find the answer to my problem.

I am trying to get the distance from the insertion point of a block and the maxX, maxY of an attribute of the block. My routine works fine when there is no UCS, however, the MaxPoints I get back when there is a UCS present is different. This is the line of code I'm using.

AttEndPt = NewPoint2d(attref.GeometricExtents.MaxPoint.X, attref.GeometricExtents.MaxPoint.Y)

The point returned is different if there is no UCS and when there is a UCS.

Any suggestions would be greatly appreciated.

thanks

Perhaps like this

AttEndPt = New Point3d(attref.GeometricExtents.MaxPoint.TransformBy(blkRef,BlockTransform).X, _

attref.GeometricExtents.MaxPointTransformBy(blkRef,BlockTransform).Y)

Thanks Hallex,

It turns out it was more of a problem in my logic..got it working the way I needed to.

The saga continues..... Although I have altered my logic, still have an issue.

What I really need to do is find the coordinate that represents the end of an Attribute value when there is a UCS present.

Have tried using the GeometricExtents, with and without the transformby and can't seem to get where I need to be.

Not sure of what logic to use, try and get the length of the text of the Attribute value, then apply that to the insertion point, but I can't seem to do this with UCS coordinates.

Can anyone provide some insight or any suggestions on the easiet way to do this?

thanks
