I need to split the model (and save the parts to an assembly) shown in the picture along the composite curve (blue line). The split function however will not accept this as input. Any suggestions?
I don't see a picture, but you need to turn that line into a face first. Try using surface fill (this is where that picture would help)?
turn the curve into a surface and use that surface as the splitting tool.
This curve does not lend itself well to creating a surface. It wont extrude as either "extruded surface" or "ruled surface".
Sorry the picture did not come through, there was an error when I tried to post. I did not believe that this post went out at all.
Like Charles says, you can't split a part with a curve. If that is a surface model, you can't split surfaces into separate bodies.
If you view the curve from the side, you should be able to convert it or th edges it was made from into a sketch, and then you can use the sketch, or an extruded surface to split the solid model.
Yes, I know you cant do a split-part with a curve, thats my complaint! Sure would be nice if we could use curves in this operation. Its not a surface model (anymore) but it probably would have been easier to break out those surfaces during that phase. I finally did use a 2D sketch (from the composite curve) to break out those bodies. It wasn't perfect, left a couple of little slivers, but it will have to do for now.
Another issue I have with the Split function is its inability to project a sketch in just one direction. There is a cargo door on one side of this fuselage and when I select its sketch Split wants to create the door on both sides. Very limiting!
You can't check the single direction box?
I see no "direction" for the split-part operation. Do you mean the check boxes for whether or not you wish to keep a seperate part?
Split can split out something on only one side, but you have to use the check boxes to only accept the item on the side where you want it. Plus, in order for that to work, the model would have to be a shelled out solid. Sounds like you need a good book or a class or something.
A work around is probably to let it split on both sides and go back and fill the side you do not want to split using surface split.
Yeah, I tried that. It works, but still leaves a seam in the model.
Yes, I found that I can an item unchecked during the split-part operation. Unfortunately it just left a big hole in the model when I used the split features to construct an assembly.
BTW, I do have a book on surfacing, perhaps its lacking a bit.
For a split-part operation, is there an advantage to using a shelled solid as opposed to a bunch of thickened surfaces knitted together?
Help > SolidWorks Tutorials > Special Types of Models > Mold Design > Next (at the bottom). Go to the page about "Parting Surfaces". This will show you how to create this parting surface to create the split. This is to create a parting surface external to the model for mold tooling, you want to actually split the model itself, so it needs to be an internal surface, not external.
Also, if this is a surface body, or if you just want to split the face on a solid body, you need to use the "split face" feature, or trim tool, not the "split" feature (which is for solid bodies).
Thanks Charles, that looks interesting.
I will work through that tutorial
Thanks all for the tips and info.
Sorry I took so long to respond, got tied up in other things!
