Q - question

Searching for hatches with missing Area property.

A - answer AutoCAD drawings may contain hatches which - mostly due to the loss of associativity - do not have the "Area" property and so you cannot use them to summarize the total area. For area calculations you will need to fix them first - reconstruct their boundary curve and re-create the hatch.

To identify such complaining hatches, we made a LISP utility SelHatch0 - it selects all hatches that do not contain the property Area - so e.g. the Properties windows doesn't display the area of such hatch object.

You can download the SelHatch0 utility from, laod it with APPLOAD and run it with the command SELHATCH0. The complaining hatches will be pre-selected for editing.
