Does anyone know how to make a grid shell structure wrapped in an organic form. I have recently migrated to ArchiCad 15 and I was able to do the substructure of the building using the shell tool. I also tried using solid elements and extrusion for the grid shell but it doesn't maintain the parallel lines of the grid shell since I lined up the 'operator' elements in 2d 'plan and elevation'. So it doesn't work properly since my structure is curvilinear. I have attached a rough 3d of the model. <BR /> <BR /> Thanks in advance</R></DIV><BR /><IMG src="http://community.graphisoft.com/t5/image/serverpage/image-id/70998iC953F1764FAF21DB/image-size/large?v=v2&amp;px=999" border="0" alt="rough 3d.JPG" title="rough 3d.JPG" /> Wed, 24 May 2023 17:03:25 GMT Anonymous 2023-05-24T17:03:25Z https://community.graphisoft.com/t5/Modeling/gridshell-perforated-curvilinear-mesh/m-p/191528#M103830 <DIV class="actalk-migrated-content"><R>Hi, can someone <B>please help</B> me.

The undulations might b*gger up this approach, but if the mullions are strictly radial and circumferential it should work. You might even be able to do it with a single profile.
