hi,
i am designing a diving tower and i want to blend the main volume and the additional volumes for the platforms seamlessly, as if it was only one big volume. i have already tried making holes on the main and connecting the edges of the additional surfaces with loft, blendsrf, patch, and even networksrf.
loft gives a very close solution to what i want, the problem is that it gives these sharp creases.
can anyone help? i would be grateful.
the pipe trim workflow, albeit a large version of it will be your friend here.
trim a hole in the main forms, then trim the platforms back to make a gap that defines the shape of the blend you want. Then use blendsrf to fill in the gaps you created. /
see this video-
Creases like this, in my experience can occur when youâre asking Rhino to create organic compound curvature using degree 1 information when it should be degree 3 information.
I would recommend analyzing the input data and checking the degree.
Also, Iâd recommend checking the composition of density of points within that data to determine if youâre also asking Rhino to compile extremely inconsistent densities of data together, i.e. if one curve is say 20 point density and one is 200 point density.
And, checking whether theyâre poly-âlinesâ or poly-âcurvesâ or have kinks in the original curve network etc.
Hence, rebuilding curves etc. will help determine a more consistent and compliant data set to create a geometry with less creases â imo.
I personally have a âwork modeâ display mode that shows as much data as possible i.e. isocurves etc.
Without more information, those are just my initial ponderings on this matter.
Your objects seem to be SubDâs.
As mentioned here, you can use SubDFuse in Grasshopper and QuadRemesh to do this.
The fusion works just for two SubD objects at a time. Youâll have to do the fusion in sequence for all your platforms.
Doing this with Grasshopper allows you to use SubDâs with vastly different subdivisions and do changes basically anytime. Make sure to also check the new Sharp command in Rhino 8 WIP.

thanks for the fast answers! i have used the first method suggested by @theoutside, it looks perfect!
well done!! looks great
I noticed that you use some very bright display mode that makes it difficult to see the general shape of the model with deep shadows and highlights. You may take advantage of using some custom viewport mode that could represent your designs in a more contrasty look. Here are plenty of nice display modes to choose from:
