Re: Knit surface problem???
Hi Nan,
Can you please run the SOLIDWORKS Rx tool and look at the diagnostics results for Graphics Card Driver?
I have opened the file on my machine and do not get the same issue as you.
Could this be graphics driver related?

Re: Knit surface problem???
Hi Ha Hoang,
Your graphics driver should show a green tick and be listed as supported and up to date.

Re: Knit surface problem???
I should also point out that I am using SOLIDWORKS 2018. But I would still suggest you check your driver. If I open the file in 2017 I do get the issue.

Hi Ha,
You can view graphics card and driver combinations on the SOLIDWORKS website.

Re: Knit surface problem???
Thank you so much Lewis. I can fix it with gap control. Btw, when i knit surface, there's always an error "pieces can not be joint into blahblah. Can you show me how to check where's the error, overlapping... and how to fix it. Thank you again.

Re: Knit surface problem???
Hi Ha Hoang
I have attached the repaired file.
I deleted the problematic face using the delete bodies command.
Knitted the rest of the model together.
Applied a new filled surface command to re-create the face.
Knitted the new face into the rest of the model and selected the create solid option.
Hope this helps.
Thanks,
Lewis

Re: Knit surface problem???
Hello Ha,.. I see it as well but... for Knit2.. you should apply Gap Control ...(image attached)
...btw,.. when you see something like this.. and "Check" still will not report a error,.. do yourself a favor,.. do a test...for instance... export to Parasolid (native kernel no translation,.. brep is as is..).. and import (again, brep should be the same, no translation).. voilà ,..the knit error is still present.. and would need to be repaired.

Re: Knit surface problem???
Thank you. It's work. But i don't really understand, when i Knit, there is always an error "pieces can not joint into blahblahblah", can you show me how to check overlapping and fix it.

Re: Knit surface problem???
Hello Ha,.. for surfaces, always build in tolerance.. that is, overlap and flexibility when trimming/knitting.
Your model is a good example ( well, my constructive criticism) of what not to do when knitting edge-to-edge trimmed surfaces.. that is, you're edge tolerances are "0". (no extra material or tolerance... )
Here is the simple analogy,... just imagine "stitching fabric"... you need extra material (tolerance) or seam overlap to stitch your panels(surfaces) together.
Also imagine your above model,.. edge-to-edge knitting,,.. if you do not have enough material (edge to edge) for your stitch,.. when you pull at the seams,.. the stitch and fabric will tear apart... (not enough allowable tolerance or material)..

Re: Knit surface problem???
...something else to mention about trim tolerances.. and how you have trimmed using 3DSketches.
A 3DSketch is another inaccuracy added to your trims and knits... so, think if it as fabric fraying.
