WHY Archicad does not smooth curves

Unabend — Mon, 27 Sep 2021 18:26:24 GMT

Hello guys!
It is my first post in this precious forum. I am starting to use Archicad after many years of Revit. And I'm a bit panicked 🙂 For example, using the Morph tool, I found that the program, drawing a cylinder, creates a surface divided 36 times, therefore polygonal! I saw that if I have to fillet a corner of a solid, you can choose the number of segmentations, that's a good thing, but the cylinder remains segmented ...
Tell me it's not true, tell me it's just my mistake, it's not possible that in 2021 such expensive software still has this problem.
Thanks!

Greetings @Unabend,

To increase the number of edges, go to Design -> Modify Morph -> Modify Segmentation... and activate the double segment option for faster action, repeat these steps to increase in several more times.

Hi Qualifa and thanks for the welcome 🙂
OK, your suggestion works perfectly for objects made through the Morph tool.
But this "segmentation" unfortunately also exists in architectural objects, cylindrical columns or curved geometry floors ... If I make a column, inserting the parametric column present in the Archicad library, its generating circle has 36 sides, and not there is no way to increase them.
A friend suggested to me a way, but not completely decisive: enter the settings of the "magic wand" and enter a much higher value of the segmentation of the curves. Consequently, if you make a circular slab for example, just make it using the magic wand tool, and its edges will be perfect. If you do it normally, its edges will be polygonal.
What a pity 😞

Approximation, you can't do without it. Yes, it makes it difficult to visualise small architectural forms, but with smoothing (I hope you removed it for the example) and visualising the exterior at a certain distance, this aspect will not be noticeable.

What do you mean with "but with smoothing (I hope you removed it for the example)"?

thanks!

In the 3D display presets there is detailed shading, selecting this option causes objects to be smoothed.
View -> 3D View Options -> Detailed Shading

I was in Detailed shading mode! No difference, because is the object "construction", not the shading that makes difference... If you see the same object in Wireframe, you will see the "grid" of 36 segments of my cilynder column 😞

there are some GDL scripts that can help with this too. For example take a look at some of the scripts for things like the Elbow 25 object

you can open the object to take a look at the script for this setting, copy and paste to your own object. ?

This is an area , which Graphisot could enhance !

Thanks Steve!

But... where are these scripts? And can they also concern columns or floors or any other parametric building element of Archicad?

for sure!

no matter what program you use, a circle is just triangles. at some point a circle is always segmented. whether you can see it or not.

The real question is why is it so important to you, that might help generate an answer that is what you are looking for.

Hello Seneca!

I dont want to see the 36 segment-faceted circular column in my 3d or planar views 😞

Re: WHY Archicad does not smooth curves

SenecaDesignLLC — Tue, 28 Sep 2021 21:17:55 GMT

So then you want more resolution.

its interesting because im using v24 and no matter what view i look at i dont see segmentation. using the column tool.

maybe share your 3d view settings.

Re: WHY Archicad does not smooth curves

Unabend — Tue, 28 Sep 2021 21:44:38 GMT

Wow! Then I install version 24? :))
In my case, I can only change the display settings if I am in a 3d window, if instead I am in a section or in an elevation I cannot ... How to do it?
In a 3D window, if instead of "vector engine" I insert "hardware acceleration", the circular wall improves a lot, while the 36-sided circular column always remains. In the elevation views, nothing changes: the curves are always faceted, but I can't even change the graphic display, switching for example to all white etc .....

you will always see the segmentation with vectorial engine. if you use the open gl then you wont have issues.

are you using a mac? that should have been my first question.

Re: WHY Archicad does not smooth curves

Unabend — Tue, 28 Sep 2021 22:26:13 GMT

No mac, windows 10 pro on a HP Z4...

Ok, in the 3D Window these settings work: when I put OpenGL the curves are more nuanced and soft, you always see the segments, but very little. If I put the vector motor they come back to see themselves very flashy (like in my previous images).
Instead I can't change the situation in Elevations and Sections 😞

Re: WHY Archicad does not smooth curves

SenecaDesignLLC — Tue, 28 Sep 2021 22:33:54 GMT

hmm can you share a screen shot of the elevation or section?

even if i show a wood column with timber variation i dont get extra lines. jus the outer lines you expect to see.

Hello Seneca! See my previous post wit 4 images (2 axonometric and 2 elevations)...
