- Part 1 of the Mesh Modeling in SOLIDWORKS series. This video focuses on working with "graphics bodies" (mesh files, such as stl, obj, 3MF, ply, etc... imported directly into SOLIDWORKS).
Note Part 2 can be found here: • Mesh Modeling in SOLID...
Topics covered include:
Overview of mesh geometry
Uses for mesh geometry in SOLIDWORKS - Visual Reference
Uses for mesh geometry in SOLIDWORKS - Geometric Reference
Main Body Types in SOLIDWORKS
Graphics body clean up tools
Decimation
Adding Sketch geometry to a graphics body
Surface from mesh
Body Compare - แนวปฏิบัติและการใช้ชีวิต
Thank you for this. It's the first time I've had to deal with meshes in 20 years of SW & the video has helped a lot!
Thank you for watching my video I am glad it is helpful.
Thank you for explaining all of this. I have been missing out on many features and running an ineffective workflow.
Thank you for your comments and thank you for watching my video.
Thank you so much! I'm a self taught CAD modeler and this helps tremendously
Excellent, I am glad it helped. Thank you for watching my video.
Hey Marlon, thanks for this extremely helpful presentation, part 1 and 2. I will definitely recommend this to my user group.
Ivan thanks so much for watching my videos. I am happy to hear that you will recommend them to members of your user group.
This is so informative. Bless you for this
Thank you for your kind words. I am glad you found it informative.
Can’t believe I am just seeing this in my feed
Hi Marlon, do you have any tips or ideas how to patch a surfaces like stone
Thanks so much for tNice tutorials video, it helped so much!
So glad it was helpful. Thanks for watching my video.
Hi Marlon, do you have any tips or ideas when a Graphics Body doesn't property convert to a Mesh Body? I have some stls, that are leaving a lot of holes in the surfaces when I try to convert them, but they look file when they are imported as graphics bodies.
Hmmm... without seeing the files you are importing I can only speculate that though the graphics bodies appear correct when imported into SOLIDWORKS as a graphics body there is a condition within the mesh that is causing the holes when the more stringent requirements for a mesh brep body are applied during conversion. In the past I have seen this sort of thing when converting to a mesh brep body when the original mesh has co-located or overlapping facets and also when the original mesh has disjointed facets (facets that appear to share an edge but don't). A google search for "mesh errors" will show many results that give explanations and examples of overlapping facets and disjointed facets. Disjointed faces in SOLIDWORKS are easy to spot because we color the edges of the face blue. You see this blue color when the mesh body is converted to mesh brep as well. Sometimes delete hole can be used to fill fully bounded holes in a mesh brep surface body. Hope this helps. Good to hear from you Jeremy!

Is there a way to turn off all these "mesh points" so that I can place lines without "sticking" to those points?
you should be able to control the snapping to mesh vertices with the following system option:
Tools -> Options -> System Options -> Sketch -> Relations/Snaps -> Snap to endpoints...
This applies for all body types. The reason it is more noticeable on mesh based geometry is because there are a large number of facets in a faceted model, each with three vertices.
Thank you for watching my video.
My mesh file presents "topological errors". How I can fix?
Mesh files have the same watertight/manifold rules as SOLIDWORKS solid body geometry. This is especially true when you attempt to convert a graphics body to a mesh brep body. As a graphics body the tools in SOLIDWORKS allow you to remove offending facets in different ways. This can resolve overlapping and intersecting facet issues. If the removed facets present a problem you can fill the hole by converting to mesh brep and using something like delete hole or other features to fill in the hole. In SOLIDWORKS 2022 or beyond this may create a hybrid mesh body.
Note that there are also many free mesh editing tools available for download that have automated tools for cleaning up the mesh. The issue with these is that the run an algorithm for which you may have little control so the result may not always be what you want.
Thanks for watching my video.
@@mbanta excelent!!! Thanks Marlon. Your videos is very good. ✌🏻
Geeze. This is basically re-modeling a triangular "fractured" surface. I will gladly pay the scanning service to do this so I get a "real" solidworks SOLID.
However, you need to know some basic surfacing commands, which most SW users do not know. Good thing I have reviewed and applied.
To clarify the term "re-engineering" = redrawing the "fractured/mesh surface" → "finite surface" →solid geometry.
Also, that [Surface from Mesh] →"FACETS" command uses "calculate" as both a selection filter and a "group selection" command. So, then you basically just blindly "drop the tolerance" and "click calculate" to grab a massive amount of fractured surfaces to turn them into a single surface.
An "alternative" is to grab select points and "geometry fit" a rectangular surface, circle, cylinder wall,...etc. Assuming, that a uniform shape was scanned.
Thanks for the video series.
Thank you very much for watching my video. I also greatly appreciate the feedback you have provided and would welcome the opportunity to speak with you to better understand your ideas.
One thing I would say is that not all users have the ability to work with a scanning service. I would also say that with the hybrid mesh and mesh brep tools we provide, getting a "real" solid is often not even be required. This can save users quite a bit of time and resources while still allowing them to reference and incorporate mesh geometry in their models. The second mesh video in the series discusses this in more detail.
