Get Bounds of BlockReference Autocad 2009

[Anonymous]

// Have a BlockReference name: acBlkRef

Extents3d acExt3d = acBlkRef.Bounds.GetValueOrDefault();
double acHeight = Math.Abs(acExt3d .MinPoint.Y - acExt3d .MaxPoint.Y);

Hi everyone, I have a code to get height of BlockReference like this.

It works fine in Autocad2014. But in Autocad2009 using VS2005, the "BlockReference class doesn't have contain 'Bounds'" Error appears.

So is there any way to get height of blockreference, thank you.

Hi,

You can use The Entity.GeometricExtents property which return an Extents3d instance instead of a Nullable<Extents3d> and works with all versions from 2007 to 2017.

// Have a BlockReference name: br

Extents3d extents = br.GeometricExtents;
double height = extents.MaxPoint.Y - extents.MinPoint.Y;
