Can someone enlighten us on the various unroll / smash commands and what to expect?
UnrollSrf = best option for unrolling (near to) developable surfaces?
UnrollSrfOld = ?
UnrollSrfUV = depricated? but no replacement…
How do Smash and SmashOld relate to this?
And what about Squish?
My take is that all these commands attempt to create a flat version of a Brep, best to be used depending on the input and intended use. Is there a comprehensive list of the use of these various commands?
Alarming to me is the fact that there is (apparently) no longer a command comparable to UnrollSrfUV where the parameterization of the input surface is preserved. This breaks a powerful workflow to unroll a surface with UV’s preserved as a means to create a flat canvas to model on the 3D surface. The UnrollSrfUV command in combination with FlowAlongSrf seems no longer possible in V6. Also see the help on UnrollSrfUV for V5
It seems Squish and SquickBack are intended to mimic the unrollSrfUv -> FlowAlongSrf workflow yet a single first test revealed it to lack crucial functionality the previous workflow had:
- SquickBack is limited to curves and points and even only on a 2-D pattern
- SquickBack is not linked to the input geometry so moving/editing the input will break usability
- SquickBack cannot be applied to other 3D surfaces but is limited to the single input only.
- SquickBack does not allow for tweaks in the parameterization (eg moving controlpoints in 2D slightly to position the flowed geometry on the 3D surface)
Please bring back UnrollSrfUV or parameterize the Squish result
Side note: FlattenSrf Command does not flatten a surface! it creates outline curves, what is it’s intended use and why is it named FlattenSrf?
Please provide a comprehensive list of flattening tools
please make sure such valuable workflow as unrollSrfUv -> FlowAlongSrf is not depricated.
