Face and Shape of Specific Area

Ben Ritter · 24 Mar 2020, 15:07

Is there a way to create a face with a specific area? I'd like to draw circles or polygons with a specific area.

Thanks.

Draw a the desired face shape [it can be any size], select that face and then activate the tool.
The face's initial area is reported in a dialog, type in the desired target area, then OK - the face is then rescaled to have the desired target area...

TIG, thanks so much.

TIG, tried it and it doesn't scale properly. Working in sq. ft. units.

Thanks. Ben

Bum !
I'll look at it asap...

I just checked it out... and in m² and ft² it works just fine for me ??

What units/precision do you have set for your Model Info > Units > Area ?

Can you attach a simple SKP that's causing you issues ?

Architectural Units, accuracy at 1/16".

Attached is the file. Original circle about 78sf. Larger Circle was supposed to be 100 sf.

Perhaps it's the way the units are entered?

When I try your SKP I get the wrong result too !
When I test it myself it was OK...

BUT now if I test it with a circle around the face it does scale oddly.

If I explode the circle first it works OK...
So something is adrift...

It's because the scaling transformation affects the face's vertices, and when it's a simple outline they get process individually, but when it's a circle they get processed repeatedly and so the scaling is then way off !

Leave it with me for a while why I invent another transformation method !!

TIG,

OK, thanks.

I get the same result if I explode the curve or polygon. Simple non-curve lines around a face work fine.

Here's v2.0
https://sketchucation.com/pluginstore?pln=TIG_scale_face
I've fixed it to cope with all face perimeters - i.e. circles etc...
Download the RBZ and install...
Please test it and report back...

TIG, Great. No problems. Thanks so much for your work on the extension.
