<div>just a reminder, I often do this kind of mullion creation in GH to mimic 3dsmax sweep modifier, all I can say is that sweep component in GH is t0o slow if you have hundreds of rail to work with.with NURBS srf as end result. I ended up redoing all definition to output them as mesh instead, with iteration slider to adjust its smootheness. (basically trying to mimic 3dsmax sweep modifier)</div><div></div><div></div><div>As seen in the images i have a stepped profile through which i want to sweep my profile shape. But I need the normal of the extrusion to be towards the centre. I hope that makes sense. Whats the best way to do this using grasshopper? how do i align the sweep towards the centre if i have to sweep these all around the circle? Thanks in advance</div><div></div><div></div><div></div><div></div><div></div><div>download sweep profile for 3ds max 2023</div><div></div><div>Download Zip: https://t.co/Yn58jmOlmH </div><div></div><div></div><div>You need a guide vector at each connection to align the mulion profile. The best way to do that is actually to turn your line network into a mesh (using the Weave Back component from Weaverbird, or else just by making a mesh yourself in Rhino) and use the averaged mesh vertex normals. I have internalised such a mesh in the definition below.</div><div></div><div></div><div>I have a couple of help questions about fine detailing onto a sweep profile tool and the first is can you create a texture map from the sweep profile tool with no texture on which then can be drawn onto as doc in Z2 (or other graphics program) then appalied to the model as a texture then use edit>draw masking on to trace the detail then inverse the mask and use edit>draw>move to bring out the detail? Having said that I would like to know of other ways to detailing onto a Sweep Profile Tool. The second question is about the thickness of the sweep profile tool model how do you make the model solid?</div><div></div><div></div><div>quote: The second question is about the thickness of the sweep profile tool model how do you make the model solid?</div><div></div><div></div><div></div><div>You have a second windows curveline for the thickness :)(T Profile)</div><div></div><div>What is the problem? The sweep profile gives always a solid model </div><div></div><div>Pilou</div><div></div><div>Ps Little trick for the 2 windows</div><div></div><div>If you take a point and make an Outdrag-Indrag(without release), the curve becomes a straight line and inverse </div><div></div><div>Pss For make a complet solid or Not, just move the first and last points </div><div></div><div>Of course you can also just move one point for just one hole</div><div></div><div></div><div>When I use masking or inverse masking and the tool>deformation>inflate neg the model/mesh gets distorted when applied (I have divided the model several times and get the distortion) - I tried the inflate neg with masking and inverse masking on the sphere3d and no distortion (sometimes I get some specks on the model) so I think a solid model from the sweep profile would allow to use the inflate neg of masking or inverse masking from sweep profile tool with cleaner meshes. I have tried adding adaptive skin - it looks to help some but some distortion.</div><div></div><div></div><div>For future reference, you need to make the U shape spline editable if it isnt already, then rotate its axis 180, not the spline itself. This is because the sweep object it reorienting the spline, so how you rotate it makes no difference.</div><div></div><div></div><div>There's this video that demonstrates modeling a globoid worm gear, and it's method is calculating the parametric equation of each tooth profile and generates the worm directly. However, I find this"adding material" method against the natural sense of worm making process ("removing material"), and that' where my question came along.</div><div></div><div></div><div></div><div></div><div></div><div></div><div>The part I'm struggling with is the 3. part because I cannot find the suitable function to sweep a profile along two rotating axes at the same time. As you can see in my sketch below, the first axis is around the center line of the hourglass and the second axis is around the gear.</div><div></div><div> df19127ead</div>
