how to get smooth arcs

Anonymous — Thu, 02 Mar 2006 05:38:50 GMT

I'm new to AC.

I'd like advice on how to get an arc drawn with the arc/circle tool to be smooth, not segmented or rough. Is there a setting for this tool to do that?

Thanks for any help.

What, no takers? This is your chance to show your superior knowledge.

The arc tool does that on it's own. There's nothing to tell.

Are you using the arc/circle tool (which always draws round curves, not segments) or are you magic wanding a curve in place?
The magic wand has settings for smooth curves or best fit line segments.

OK, my confusion. I was trying to do something that's really outside the scope of this forum (and over my head) that ended up looking unsmooth.

Sorry to bother you with it. I'll stick to legit concerns from now on.

What did you try to do?

I would also regard the arcs that AC produces as being reasonably smooth.

I recall that Autocad used to have a 'viewres' setting to control the level of arc resolution. With current technology this resource saving item (speed vs image quality compromise) has probably been done away with. The arcs that ArchiCad create should really not be showing up as octagons or other polygons.

Is it possibly a video card problem?

Check and play around with the '2-d redraw options' under 'work environment'

If you're not having any joy, post a sample image of the problem.

I tried copying and pasting an arc from AC9 to Photoshop to produce marketing graphics. It looks jaggedy in Photoshop, which made me think it wasn't smooth. Frankly, I know even less about PS than AC, so it might actually be smooth.

I might just spend the money for a graphics drawing program (I'm looking at Intaglio for the Mac) for that kind of thing.

Again, thanks for the input, and you can consider this topic closed if you want.

Generally you cannot copy something graphic from Archicad into another program.

You either need to export it through the Publisher system or print to PDF.

yes arcs are smooth unless it is a 3d arc then you are out of luck. Being a BIM system - that's too bad.
Too bad too if for some odd reason you are copying an arc from plotmaker back to archiacd.
