<p>Hello,</p>
<p>I was trying to create a cushion out of a curved, flat, vertical surface without much success. I combed through many discussions surrounding Kangaroo and was able to salvage some components from different definitions. However, the end result is nowhere close to what I have in my sketch. Hopefully, you guys can give me some pointers.…</p>

<p>The curve is referenced in from Rhino and then used as a centerline for the cushion. I was only able to inflate it on one side.</p>

<p>In addition, I could not create a surface out of the output points from Kangaroo. The resulted surface seems to fold onto itself although I already have the expression for input U to be x+1.</p>

<p></p>
<p>Here are my 2 questions:</p>
<p>1) How can I inflate the mesh from both sides?</p>
<p></p>
<p>2) What is the best method to create a surface from these output points?</p>
<p></p>
<p>I attached both the Rhino and grasshopper file here. You will need Kangaroo 2 to open the definition.

<p>Hello,<br/>I'm gathering information on modeling and calculating ETFE cushions. I'd like to ask if Kangaroo will allow me to find the shape of an ETFE cushion knowing the modulus of elasticity of the ETFE membrane and the pressure of the air inside using units such as Pascals...<br/>I have been using kangaroo already for tentative models, but I am searching for a tool that will allow me to work using units. Does anyone know if kangaroo is able to work with units? I'd like to be able to calculate the resulting forces on the borders of the ETFE cushions, to incorporate tensile cables and see how the thing performs... is this possible on Kangaroo? Or is there another software that can help me with this?<br/>Any info on this will be welcome.</p>
<p>Thank you!</p>
