Distributing inbuilt 3D panels (e.g., pyramids) seems to work in that their sides remain flat (is it true in all cases?). However, we are encountering problems generating straight edges and flat triangular faces when distributing custom variable panels, for example 3D pyramids. (See image) Is there an option to enforce planarity? And/or an option to select a mesh (which perhaps might be the way to go, by implementing a similar command that would distort geometry by shifting vertices and keeping edges and triangular faces straight).

More generally – it would be good to see some additional options for distributing 3D variable panels with the goal of generating triangulated surfaces, flat quads or developable surfaces.

3d custom paneling deforms a given module morphing from the module bounding box to the unit grid (bounded by the 2 grids). this is why it can be hard to enforce special case results, such as planarity.

If you need to enforce planar pyramids (like in the attached case), why not use ptPanel3D? There is an option in this command to output meshes.

Hi Raja -

Actually we are hoping to be use the ptpanel3dcustomvariable command but enforce planarity by selecting meshes. Is there any work-around that would allow us to select meshes here so we could for instance... morph or change between different panels in reponse to an attractor point or curve?

Hi Annie,

Sorry it took long to reply.

Are you working with same structure meshes, or ones that are different?

hi raja  -

no worries about the delay,

we would be selecting different meshes for instance running the command with the list or mean option...

 

I am working on adding support for meshes in ptPanel3DCustomVariable command.  It will use any set of meshes from a list, but will need to have exact same structure meshes for the Mean option.  Morphing between 2 meshes that have different structure is very challenging.  In this case, one suggestion is to use NURBS surfaces and once populated, convert to mesh.

Annie,

Please try the new release and see if it supports the functionality your were looking for.
