Smooth Your Models

I always appreciate a keen eye to detail. This is especially the case when it comes to noticing the often hidden details of a computer generated image that looks like the real thing. More often than not, the tessellation quality is an oversight or you may not be aware of how to make your models more realistic by smoothing out the curves. What do I mean by smoothing? Look at this example:

These images were generated inside SOLIDWORKS and the quality differences are clear. Often, the default setting is ok, but whether you’re taking screen shots in SOLIDWORKS or rendering the model with PhotoView 360 or SOLIDWORKS Visualize, there’s a critical option to change to get the most realistic representation.

With your model open (this is a file specific setting so be mindful of your document templates), go to Tools>Options>Document Properties>Image Quality. Increase the slider of the “Shaded and draft quality HLR/HLV resolution” as shown above. This works for assemblies too!

PhotoView 360 and SOLIDWORKS Visualize are dependent on this setting and will use this model resolution (also known as tessellation quality) when the model is rendered.

Using SOLIDWORKS Visualize to render files not coming from SOLIDWORKS? You can change the tessellation quality after the import with SOLIDWORKS Visualize Professional! Select the part and find the Tessellation section in the properties pane.

Otherwise, when you import the following document formats in SOLIDWORKS Visualize Standard and Professional, you can specify the tessellation quality.

Supported file types: sat, sab, asat, asab, model, exp, session, CATPart, iam, x_t, xmt_txt, x_b, xmt_bit, prt, par, asm, psm, stp, step, wire, iges, igs.

The slider works well, but if you have specific requirements on the tolerance of the tessellation, you can use the advanced settings.

Please share your renderings from PhotoView 360 or SOLIDWORKS Visualize by sending the images to
