Meshing in Rhino

TweenCurves is a Rhino 5 command. As an alternative, you can create a loft between you start and end curves, then extract isocurves to use. You can also use the MeanCurve command as @eddi suggested. The one limitation is that it will gives you the middle curve only.

Thanks @rajaa. Could you please give your suggestions on the discussion topic that I posted recently.,

I’m keenly looking your opinions and approach for this.

Many Thanks

There is a possible solution in PanelingTools, and it can be solved the way I explained above. I understand that it might be a bit cumbersome.
A subdivision mesh solution is probably more appropriate. @piac do you have thoughts about a mesh subdivision solution is this case?

rajaa could u please tell me how to do same meshing
by taking rectangle instead of polyson

hii rajaa could you please tell me how to do same meshing by taking rectangle instead of polygon in above figure

could u please tell me how to do same meshing by taking rectangle at base instead of polygon

A rectangle is a polygon.

Means polygon with 4 sides

@rajaa please help with creating quad meshes by taking reactangle with 4 sides as a polygon as a base surface…i only want to join quad meshes between
Curves. I am using tween curves but I am unable to join meshes like u did above.i am attaching a pic also please help me.

I created the mesh below by following Rajaa’s instructions with “square” substituted for “hexagon”.

A rectangle with an aspect ratio not equal to 1 would require modification of the method.

@user2837 How much experience do you have using Rhino? Are you a student?

Yes I am student

@davidcockey can u share the command history for above creation with me

What modification did u do other than rajaa’s suggestion can u explain in detail …it would be of great help.

@davidcockey I cannot open ur file as I am using rhino version 6 only so please explain here in a bit detail.

Attached is a V6 version of the file.

You can easily find the commands to use to create rectangles and circles. The location of the seams can be adjusted using CrvSeam. The other commands I used are included in Rajaa’s instructions.

Most participants in this forum are willing to help others learn as long as it appears those asking questions are also trying to help themselves. Learning requires work, not just copying what others have done.

If you use Rajaa’s method on a rectangle you will find where it does not work as you would wish. Then think about what would be needed to achieve what you want. After you have done that you will be able to better ask for assistance.

@davidcockey thanks a lot. I am working on it brother…after failing many times I asked here. I am also keen to learn. Thanks for ur suggestions. I appreciate it.

@rajaa @davidcockey @eddi I Want to generate quad mesh as shown in figure attached at the interface between two perpendicular cylinders but i am unable to do it. I am attaching the file and figure for reference. Any type of help would be highly appreciated.

First used _OffsetCrvOnSrf (Target big cylinder, from Edge) for “Guide Curve”
This provides _QuadRemesh

when i am saving my file as a .gdf file in rhino 6/7 it is showing file writing plug in failed. how to solve this issue
