applying 2D fills simultaneosly

Anonymous — Sun, 13 Apr 2008 18:24:59 GMT

Hi all,
I am working on plan where i need to apply a 2D fill on many closed polylines ( lots and lots of them ).
Is there any form to do it at ones ? The only way I know is one by one with fill tool selected and clicking with the magic wand on every polyline.
Any help appreciated.

regards,
Sergio

If they are regularly spaced you can do one and use the Multiply command.

This is a recurring problem with neighborhood dwgs when you want to create a quick massing model with slabs, I have never found a way of avoiding the thousand clicks.

But if all you want are fills, and the situation is something like I am describing above for a solid-void diagram or something like that, perhaps a workaround could be: select all polygons and check the zone-boundary checkbox (repeat for lines if you have lines too), draw a fill or a zone-boundary taking up the whole drawing area, select the zone tool and space-bar click to create a zone taking up the voids, and now explode the zone. You have a fill for the voids, the negative of what you want, so putting a continuous background fill behind it will give you the look of the fills that you were asking for.

Theorectically we should just be able to place a fill around all polygons, then subtract the extra areas by magic wanding inside the fill, but outside the polygons.

Unfortunately ArchiCAD has never been good at pulling this off. I mean it can't even figure out how to fill in a donut shape.

Cheers,

Stuart: there is no single one with the same shape

Ignacio: at the beginnig I got a "region not found around this point
message". Afterwards AC would not even notice the polygons were there and did a zone the size of the fill.

Link: Theoretically. I have tried different approaches and it seems it only work with one polygon. Interestingly, if the fill edge goes over the polygons ( even many of them ), AC "detect" them and can do the trick. But just on them.

thanks to all,
if you have any other ideas please do not hesitate to comment them !

Err for some reason I skipped the word 'polyline' in my post. It does work for me with a polyline. Try a polyline or a line rectangle for the frame, check 'zone boundary'.

If it still doesn't work, assuming all the polygons and lines join up properly and that their zone boundary checkboxes are checked, maybe a factor could be polygon count --I would try doing a chunk of the neighborhood plan at a time.
