In order to simulate this complex custom construction you may choose :
a. Build it in Capture
A way to simulate this object is by using Cylinder hull pieces found under forms in our library. You need to modify the start and the end thicknesses of each piece and even attach a material in order to look like fabric. Then you should modify the rotation and the centre radius of each piece in order to meet the curves you need and finally to adjust the pieces together and maybe even group them in order to move them easily to the desired location of your model
b. Find a ready 3D model from e.g. a website that shares 3D models (there many of them that are completely free) and import it in Capture for final adjustments.
c. Build your complicated custom structure in a dedicated CAD software and import it in Capture
