Intersect produces disjointed curves

[pamakela]

Hi,

quite often when I perform an intersect between a (continuous) set of surfaces and a planar surface, the resulting 3D curves are not continuous. There appears to be very small gaps between the curve segments. Is there a way to fix this?

A bug or feature of SW(17)? We need to stick to 2017 for now.

Is it truly continuous? Arcs and lines making a surface is not a continuous surface. Using a Fit spline is a true continuous surface.

Thanks for the replies. This case represents the upper situation shown in SBaugh's reply. But regardless of continuity, shouldn't the resulting intersect curve(s) be connected? Connected is enough for me in this case. But these gaps.. why are there gaps? Very small ones that you can actually see only when you zoom in really close. The surfaces I use - in addition to the planar surface - are from a solid body so definitely no gaps there.

It appears there are gaps. But are there actual gaps? Have you measured? Could just be poor graphic resolution.

One way to determine if there are gaps is to extrude as a surface then you can measure edge to edge.

I have never seen this sort of bug if it is a bug in SW 2017. It would be helpful if you have an example file this is happening too that you can share with us.
