Dynamic Area Field in Block

[SG68]

This might be simple, but so might I be....

I have a very simple block that is a hatched rectangular shape, with dimensions 10 x 1.

I have added an Attribute to the block to show its area, using ATTDEF and choosing a Field, object Hatch, property Area.

This works fine when I insert the block to a natural scale. For example, if I insert the block at a scale of 1 it displays the attribute area of 10, if I scale the block at 2 it displays the area correctly as 40.

The problem comes if I try to give the block a stretched scale. For example, if I insert the block at an X Scale of 2, Y scale of 1, it should calculate an area of 20, but instead it still shows the area to be 10.

In fact, if I give the block any stretched scale at all, the Attribute for area stays at 10.

Anyone out there less simple than me can help?

You need to do a regen. Fields do not automatically update when the geometry they're associated with changes.

[SG68]

Yes, the Regen works if the block is to a natural scale but not if it is stretched

Is your hatch associated with the rectangle?

[SG68]

Yes

If it's a simple rectangle what happens if you change the field to give you the area of the rectangle?

That didn't work initially, until I changed the block into a dynamic block that can be stretched, rather than a standard block that I gave a different X/Y scale, but then as you suggested I applied the field to the area of the polyline rather than the area of the hatch and it works.

Thanks for your help
