Rhino after simple trim creating problems where none existed

Hi,
V5
The item featured in the background had non planar top and bott. It lives within an object, the whole has no naked edges.

This item I needed to add planar top and bottom.

I then trimmed with straight line the top and bottom of this item in side view ortho,
I surfaced the two planar areas with _PlanarSrf.
I join surfaces of this and the complex object it sits within again and run zoom Naked and it finds such for this item. at A B C D etc to N.

How can a planar surface trimmed with a straight line and surfaced be NakedEdge let alone then make all the edges naked ?

Let alone the other parts that normally are ok ?

I copy it and the adjacent surfaces out to a new file and apart from the ‘to be expected’ edges, the planar surfaces are now okay.

Why is it that Rhino invents problems where they really shouldnt exist, and dont exist when its taken to a new file ?

Has Rhino a limit of complexity beyond which it starts to misbehave ?

( I can’t post the entire project)

To have 19 naked edges appear on what was healthy, when all I did was trim top and bott and surface them, is soul destroying.

Its like owning a ford escort, many trips to garage, then I buy a mazda and not one problem in all the years of ownership.

I hope V8 is more stable.

What is your end goal? Are just trying to close it up to be water tight?—-Mark

Hi,
it needs to be without naked edges, no naked edges is good practice anyway, and it was watertight, to be 3D printed,
… then a simple trim and it goes nuts.

Why ?

This probably isn’t what you want.
I don’t know about you ,but we use this software that isn’t perfect and we are not perfect. The thing is we have to figure out how to solve stuff we make. Sometimes it is the software’s fault and sometimes it is ours. —Mark

I don’t see any naked edges on your object except for the expected open ones.

Hi,

exactly as I say, copy the little blighter out and all is ok, but every edge as lettered had red naked edge lines in the project it came from, and it was all joined, it was as if I hadnt joined it, yet I had.

Copy it out and it as it should be.

It is Rhino, probably been munching some wacky mushrooms !

I keep finding if I copy something out, its then ok.

Its the Ford Escort versus Mazda 323 Fastback. crazy things happening , accept it. everyone has such, then I buy a mazda, and realise escort ownership and ford parts was not normal, normal for escort owners perhaps .

That’s great, you have a solution, copy out, copy back.

Now as a point of etiquette, could I ask you to drop this recent habit of posting files that show a good outcome and not files that show the problem you want to solve. There is no way to explore the problem, come up with a theory and test its validity from what you provide. So everybody who, in the generous spirit of this forum, opens your files to try and do so is having their time wasted. Life’s too short, please stop.

Hi,
I will come at this in a different way…

I need to know how to solve what keeps happening.

I wish I could post the source file but its MASSIVE and copyright and more besides, and also its sub project. copied out from it.

yet again I get a problem, a curve where start and finish pipe command dia are .01 and .001, I split it, the first works, the second half is back to front, the .01 is where the .001 should be. Dir is same for both, so the start of the curve has arrows heading from it.

I copy it out to a new file and try again then it behaves !

I copy that back in and then run pipe command on the offender and now it works.

_RemoveGremlins

Is there a command to replenish Rhino and rid a project or in this case a child of the project, call it ‘child’a’ of gremlins as simple things are going wrong and I am spending all my time solving things that normally would be ok, like chasing rainbows. I am unable to make normal speed to the finishing line.

It is not right that I have to keep copying out and back things .

Half my day spent solving gremlins.

Rhino new method.

  1. run command.
    2 copy out wonky result
    3 run command again
    4 copy back good result.

Yes it works sometimes, not always, but surely its not right.

Rhino has a limit on complexity it seems.

Here is the pipe command one referred to, it comes from child’a’, my last post was from child’a’ . So have the gremlins been born in child’a’ or come with it from the massive project (parent) ?

is there a health check command ?
is there a way of stripping out in a save command any gremlins, does save small do so ?
