Working with IsoCurveTool

[JohnyCageII]

Hi,

i have a problem. I made 2x iso curve(1x U, 1xV) by using isoCurve tool (from RailSwp surface). My question sounds.., how can I make a shared point between discussed curves? I wont to use it for new railswp surface - for better controlling detalis of surface...The problem is described on attached picture. Thanks for yours time.

Hey Johny,

I am a little unsure what you are trying to accomplish. If you want more control over the surface, you could add more U's or V's and pick multiple edges as either the rail curves or the shape curves to generate a new surface.

Why do you want them to share a vertex? Is it not enough that they are intersecting?

Any other information would help.

such as you said, it is not enough. If you can to select the mentioned shared point then you can automatically afecting the both of curves together. Its much more usable and flexible.

Hi Johny,

Unfortunately theres not a great solution for the problem that you described. There is one thing you could try that might achieve what you want.

Simple Instructions:
1. Edit Sketch Iso Curves and Attach them
2. Go to Sub-Object Edge mode, and click "insert Point"
3. Insert points on each edge relatively close to the place where the edges intersect. (You might have to insert a few points until you get a vertice on each edge. The points look purple, the vertices are green boxes) You basically want one vertice on each edge as close to the point of intersection.
4. go to Sub-Object Vertex mode, select the two vertices
5. Click "Merge Verts"

Now they should be loosely "shared". Unfortunately this is a very loose connection, as they are "sharing" a vertex (control point) and not the actual point on the line.

Also of note, theres an option called intersect, which is available in sub-object edge mode of edit sketch, that will produce a marker at the point where selected edges intersect. This could be useful as a point of reference that you could snap to.

Sorry there is not a solution to your problem, hopefully this was helpful in some way, or perhaps it could lead you a different solution to your problem.

momentarily i working with it directly such as you wrote, but its a breakneck soulution and the output of surface and the whole workflow is not the same..:(

Yes., the connecting are very "loose" and func. "intesect" works fine, however without using iso-curve-tool :(

I add this feature to wishlist and i will hope it will solved in next time.

For this time...thanks very much for yours reactions.

Hi,

I wonder if a NURBS Slice modifier would be useful in this case.
Like the poly slice modifier, it could include options to allow the user to specify the nature of the slice (refine, split, remove bottom/top, etc.), and to also define the resulting spline and how it relates to the surface. In this case, a refine mesh would seem to help. Does this sound like a good idea? If so, perhaps it could be added to the wish list. . .
