FlowAlongSrf tool, allocation of group of surfaces


#1

Hello, I faced a problem - when using “FlowAlongSrf” I choose objects, the plan and I need to allocate the object consisting approximately of 5 surfaces and all of them are registered, but the tool allows to choose only 1 surface in all an object. What shall I do?

How to apply me on an object (with a set of surfaces) an object necessary to me?

Hi @Modeler3D

If I understand you correctly, you are trying to flowalongsrf across a polysurface, and there is currently no way of doing that. You need to construct your target surface, so that it is a single surface. You could tryto experiment with the drape command.

HTH, Jakob

Unfortunately not one way doesn’t suit me…


#6

And what if to take all points at an object and to construct on them a uniform difficult surface? Only I can’t find the tool in any way - have allocated and on them the surface was constructed.

I have solved a problem!
If to create surfaces (1, 2, 3 etc.), and after to unite all of them by means of the MergeSrf tool - as a result of FlowAlongSrf works with a set of surfaces as with one object.

Something with the FlowAlongSrf tool extremely isn’t clear to me. He places result under the chosen surface, on the chosen surface - it depends?

Hi Modeler3d - the best way to get this to be consistent is to use the Dir command to make sure U, V and Normals on the two surfaces correspond, then click on corresponding locations of the surfaces when picking them.

I thank!
If to you it isn’t difficult - tell, this parameter how exactly works:

Hi Modeler3d - this simply makes the surface U direction into V and the V into U. ‘Swap’ implies a ‘trade’ or ‘invert’.

I have understood, thanks!
