multi-gonal object... instead of circle

Hi, I noticed a problem when working with sheet metal and then converting it to visualize project.

if you notice the cone of the vessel is not cone, but multiedged cone. I used sheet metal to make it and loft from higher diameter to upper lower diameter.

If I increase detail in solidworks, it creates more of edges, however solidworks starts working pretty slow - but nowhere nearly as slow as visualize where it practically can't handle the object.

I assume revolving without using sheet metal loft would make a better shape? The problem is that all my vessels are made this way...

This can be done on the part level. Here's an example.

I doubt the way the geometry was created is causing the issue. If it were me I'd try bring just the "cone" part in separately from the rest of the assembly. That way you can control the tessellation of just that part (rather than the whole model). This may allow you to have a smoother surface without slowing down Visualize as much.

Another option would be to convert the part to step and then import into your Visualize project. Step import allows for more specific tessellation control on import.

You could also try adding some circular split lines (rings) to the "cone". This will break up the surface and force Visualize to have smaller triangle areas rather than the long skinny triangles its creating now.

Just some ideas. Not sure any of them will work?

  Apparently my assemblies are so large that it automatically decreases detail or something. I didn't expect that this would import models with the same mesh quality...
  I need to set "shaded and draft quality" to higher in order to get better results in visualize.

    Yes you definitely want to increase the image quality setting in SW and it will transfer to Vis.

    Yup, get that slider into the red, that is effectively the tessellation that Visualize uses.

      Can I do that just for specific parts? Or does it need to be top level on assembly?
      Anyway despite increasing that the surfaces can still be seen on the cone as the light illuminates it differently, except they are a lot smaller.
      Is there a way to eliminate that by drawing object differently or will that always show on conical objects?

        The slider works at both the part level and the assembly level but at the assembly level all the parts will take on the assembly setting. You can't have one part in an assembly highly tessellated and others with low tessellation. The only way I know of to achieve this is import your assembly into Visualize with the assembly set to lower tessellation and the parts you want at higher tessellation suppressed or deleted. Then suppress or delete all the lower tessellation parts, bring back the parts you need at higher tessellation, save the assembly and then import that into your Visualize project.

        When creating the assembly, just don't touch the slider on the assembly document properties, and it works

        You are correct. This does work! This is a complete 180 from how its worked when transferring geometry to other rendering applications in the past. This is a fairly significant nugget of gold in my opinion. DS should be putting information like this out there so the public knows about it. Maybe in the help file or maybe in some sort of "Import Guide"?

      You have to be careful with that slider. I like to run it up in the red zone as well because that gives me the smoothest geometry but the poly count builds quickly when you do this. High poly counts can easily bring Visualize to its knees in terms of performance.

It's nonsense for a render tool to treat large visible circles like some octagons!!
Why should we manually catch this for every part?

  I noticed visualize can work really slow if detailed objects are imported.
  But if you ask me visualize should import with max detail then decrease detail within visualize. And on render it should increase it again.
