When im creating a tooling split it gives me an error saying it cannot knit the surfaces together. how do i fix this? I can't upload any pictures though.
Unfortunately, it is nearly impossible to say why it cannot knit surfaces together without the file of at least some pictures.
If you have any areas where two of the surfaces intersect one another or where two or three surfaces form a T shape, that will kill the Knit.
Manual troubleshoot for your problem:
1. Make a copy of the parting surface body
2. Try to knit the parting surface with the core surface. Does the knit command work? Are there any gaps or other problems?
3. Try to knit the parting surface with the cavity surface. Does the knit command work? Are there any gaps or other problems?
I can knit the parting surface to the core and cavity surfaces but their are gaps in both.
So? Close the gaps.
Check the solid body using tools,check. If you see what are called `general faults' then you will get that error. SW will allow you to create the partingline feature and manual shutoff surfaces but if there are errors in the model, nothing will knit.
Their were general faults and i fixed them by deleting a fillet but it still wont knit the sheets together.
It is possible that you did not fix all errors. It is always extremely dangerous to build on imported models that have errors. First of all you would not be able to use Import Diagnostics once you add anything to the feature tree.
If the parting line is too much curve around (not smooth), there may be overlapping surfaces on the parting surface.
Have a close look at the surface
I think thats what the problem was, but i just ended up using a cut with surface feature and that worked so thanks anywany
One trick which sometimes solves the problem is to save the faces of the part that you are trying to knit as an IGES file and then read it back into SolidWorks - it goes through a different algorithm and can create one topological surface.
Another is to buy SplitWorks from R&B - which has a function called Island Analysis showing non-connected faces, which can cause the knit function to fail.
