Plugging holes in a hatch

[itacad]

Good morning, hatching is often used to indicate planimetric areas for a specific topic.

One way to highlight these areas on a floor plan is to create a general hatching that covers the whole area, leaving squares that will appear as holes in the hatching.

It's a very simple operation, you create the general square, you create the boxes that will act as holes and you hatch in the area outside these holes.

In the evolution of the document, it happens that these holes have to disappear and be replaced by the general hatch.

Is there a faster method than the one I use, that is, to redo the general hatching without the boxes to be deleted?
Is it possible to say to the hatching: cover that hole inside you!

 

Greetings!

Recreate boundaries and then delete the boundary will fill the hole.

 

Maybe this thread will help.

Could you create wipeouts on a separate layer to represent the open areas? To remove them, simply turn off the layer in model space, or even easier, in a viewport. That also makes it easier to select them in one go. This scheme has the benefit of leaving the original hatch untouched.

the topic is more complex than I thought (googling I didn't find any solutions)...but the example file I sent already seems to work as I need...and I don't know why!

There are actually several places with the solution, even YouTube.

If you read the thread I posted, you simply delete the boundary, if no boundary you recreate then delete. Also there is a LISP I linked.

Pretty sure was asked also over at Forums/autodesk, "Remove hatch islands"
