I am trying to create a molded. I created the parting line, parting surface, and get an error when tring to do a Tooling Split w/interlock surface "cannot knit sheets together". Any ideas?
Jim, how about posting your part and let some check or fix that for you.
I'm not familiar with the parting line/surface tools, but when I am working with surfaces, it seems like I get this message when I try to knit two surfaces that penetrate each other or make a T.
how do i post my part to get help with this issue
Your shut-off surface must be larger than the "block size".
This is a common issue in mold desgin.
Try STEP out and STEP in...
select the individual surface bodies
Save As type STEP
Selected bodies and click OK.
Then... import the surface body back SolidWorks toolbar Insert, Features, Imported...
If this fails, you can import the surface into a new part and try healing from there.
I've heard about this round-tripping before, but I can't quite see what it is supposed to do.
I just wanted to report that in SplitWorks we have a menu called "island analysis" which we use to find and browse through non-connected groups of faces and select/move them (the groups are cavity, core, side core or any user groups formed) which helps overcome knitting problems where there are small areas which are not discernable. This is in the context of creating parting surfaces with SplitWorks and not as a general tool.
Start doing a Scale for material shrink by a factor of 1.04 or 4% or whatever you need. Before you do the “Parting Line” do a “Split Line” by selecting Top plane and click on any surface that the Top intersects. After that do the "Parting Line" and select Top @1deg. Now do the "Parting Surface" and finally the "Tooling Split" and "Body-Move". Rename the "Tooling Split1" and the "Body-Move1" into CORE and CAVITY. Insert the CORE into a New Part and also insert the CAVITY into a New Part. Now you can works independently to create the sprue, runner(s) and the gate(s) and whatever you may need to get done

i downloaded the handle and followed the steps and still got the error how do i post my part to get some help with this issue
sorry to reopen this but ive modelled a part, has one solid body folder and one surface folder yet there are still blue lines and i cant knit any more...............................
I believe that the blue lines are gaps in your surface model. If they are real openings that surround an actual area, you may be able to use the Fill command to close them up. If they are don't seem to have any width, but are just places where the edges didn't knit properly, then you will probably have to modify the underlying surfaces to eliminate them. If you've got a feature tree to play with, then you can go back before the knits to see if you can make the surfaces larger before trimming them, for example. If it is imported, you may have to remake the surfaces, starting with Offset Surface with 0 offset on individual faces. With luck you can Untrim the surfaces or Extend them and then Trim again to eliminate the gaps.
You may also be able to fiddle with controls in you Knits to accomadate less-than-perfect matches between edges. This may tweak you shape.
