How to use Flow?

I try to flow a wire mesh to a sphere, here is what happened, how to solve this?

Both use project.

1. Flow on a large surface, success but the wires are deformed.





2. Flow on a small surface, strange result.

wires also deformed.

Try with a rectangular (square) face as Start ...



You can also tale a circular surface as start but you will obtain some more empty aeras!

All is depending of surfaces / Volumes...

You'll probably want to read the entire thread.

Hi Jack, there's some pretty detailed instructions in the help file here:
https://moi3d.com/4.0/docs/moi_command_reference8.htm#flow
quote:

For projective mode the target object can be made up of multiple joined surfaces if they are all smooth to one another.

In projective mode, rays are fired out from the base plane along the base plane's surface normals and intersected with the target object. The target object should be large enough so that these rays actually hit it and do not just fire out into empty space.


Do you have an image or sketch of the result you're trying to get?

Hi Jack, for your #1, one way you could avoid the deformation would be to flow curves instead of fully constructed tubes, then sweep a circle on the deformed curves.

For your #2 that's making a strange result because of this:

thx Michael,

for #1, your solution is good, but it is time consuming, we need do each curve individually.

Hi Jack,

re:

You don't need to do each curve individually, in sweep you can select a bunch of curves as the rails in one use of the Sweep command.

Here's an example:

thx, I just figure out, I need select rails curves in the same direction. if I select both horizantal and vertical, it will fail.

Hi Jack, check the placement of the circle profile curve that is being swept. If it is inside the bounding box around the rails it will use the circle from its current position. If it is outside the bounding box around the rails it will use "auto place" mode where it will automatically move and rotate the circle onto the starting position of each rail. For this case you want auto place mode to be used.

If you're still having trouble please post the 3dm model file with the curves you are trying to use so I can see what you are running into.

Hi Pilou,
Why don't you use the same process as Michael for your little demonstration videos (post 10215.8 below), I think it would be more explicit.

@ Zooen It's not the same price and for 10 - 20 seconds that is the same result! ;)
There are a lot fo screen recorders but i prefere my very simple GifCam
