Artlantis - Need more polygons!

jamespage11 — Thu, 11 May 2023 11:06:02 GMT

What's going on here? I drew some vanities for a bathroom - they're custom profile walls rotated around a very small radius, saved as embedded objects and then set into separate custom profile walls for the counters with a subtraction SEO. They look fine in Archicad, as you can see in the screen shot below, but when I import the model into Artlantis they come out with a ridiculously low number of polygons. Luckily the finish I want is a streaky, thick glaze so I was able to disguise it a little, but it still looks terrible. (Rendered image to follow) Anyone know how to fix this?

And the rendered image - ugh!

Oops. Here's one without the water.

Try creating the basins with OBJECTiVE. Create a swept profile with OBJECTiVE > Component > New Profile and select the profile type as Lathed.

This object settings include a tolerance parameter - the higher the tolerances, the fewer the polygons (see item 1 in the attached image). Item 2 shows the basin with the tolerances set to 10mm (very course), and item 3 at 0.1mm (very fine). This might give you a much better result in Artlantis.

Thanks for the suggestion Ralph. I'm sure your software is excellent, but I'm afraid I'm still not interested in buying it. Thank you.

Can anyone else tell me if there's not a way to solve this with ARCHICAD?

Based on the videos and information for AC15 it seems you might be able to do this more easily very soon.
In the meantime I might try to approach this with the Basic Shapes library parts and most likely use the dome object. Then flip the object upside down as a custom library part.

In the Basic Shapes you can set the resolution higher. You might want to try this approach within the out of the box functionality of ArchiCAD.

Thanks Graham.

That could sort of work, but I'm going to end up with a really ugly flat edge to the basin, rather than what is supposed to be quite a complex elegant curve at the lip of it.

Those AC15 shells do look like they could be the answer though..

Try to right click on the basins and "merge vertexes", and then smoothen the material with the slider.

Certainly with a complex edge that won't work. I would stick with the complex profile wall unless you can wait until AC15 is arrives and use the shell tool

Yes.

Smooth the polygons - Material Dialog.

Krippahl and Dwight, thanks so much! That material smoothness slider is magic! I can't believe how easily it works! And it doesn't even seem to slow render speed down too heavily.

What does the merge vertices function actually do? It doesn't seem to make a difference whether I do it or not, and it gives one of those scary warnings that it can't be undone..

P.S. Dwight I might actually do that. I seem to have hit a bit of a ceiling in improving my renders with Artlantis. They're looking pretty good I'd say, but they're missing a lot of what makes a truly professional looking image, and the Artlantis forum's not really much help once you've grasped the basics of the software..
