the model in the last few posts was very distorted. this is on purpose to push the setup to its limits. The intended use case is more like shown below. All the sketches that control the structure were edited to work with each other instead of against each other. the top was made as uniform as possib...

more variations, and showing the independent underside (which is structured in the same way as the top.

adjust blend segmentation points. note that the crease from back to front transitions to smooth entirely with the blend surface Merge_Blend_02_14.png adjust master layout sketches. this pushes the horizontal plane simple G1 beyond esthetics, but the blend regions hold out well Merge_Blend_02_15.png ...

new function: ControlGrid64_Surf44 new topology: start and stop a blend along the edge of a 4X4 surface. below: -the tip of the structure, close and left, has a single surface. it blends backwards into two surfaces. -the two surfaces in the back blend into each other -the blended structure does not ...

There is more work to do here for automation and optimization, but this first stab turned out waaaaaaaaaaay better than i thought it would, and it makes this 'tube capping' structure quite versatile, so i decided to commit it.

G2 is established on the mirror plane (mirrored G1 is always G2), but G2 is lost along the segmentation in this case, this loss is not easily detected, so the trade off is positive. ControlGrid64_normal_02_07.png ControlGrid64_normal_02_08.png . there are 4 parameters to adjust along the new normal ...

on the left, the blend pays no attention to how the grid crosses the center plane. on the right, the new grid forces all gridlines reaching the center plane to be perpendicular, making it mirrorable (G2) ControlGrid64_normal_02_02.png . another angle, mirror plane crease versus no crease ControlGrid...

New function: ControlGrid64_normal This is a compromise/convenience tool to take advantage of symmetry. This is a derived grid intended to take a ControlGrid64_2Grid44 as input. ControlGrid64_2Grid44 creates a G2 blend between two ControlGrid44 (of which there are several types). In the case where b...

just for fun, here are all the viewsets in this model, edited so they don't overlap. master sketches master extrusions master common common faces traced to bezier surfaces cutting points blend along length blend along width blend both (links are still in original position) CadDivision_19_06.png when...
