gooooog 10 Posted October 9, 2011 Hi i've got to grips quite well with mesh modelling but i cannot seem to be able to mitigate this shape, a hyperbolic paraboloid in 3D Cad (see attached image)... can anyone give me any guidance on this matter? Thanks Clive Quote Share this post Link to post Share on other sites

gooooog 10 Posted October 9, 2011 convert what into a surface? ive tried loads of different ways theres no guidance tips on youtube or the internet. thanks Clive Quote Share this post Link to post Share on other sites
JD Mather 12 Posted October 9, 2011 Patch might be your solution. Quote Share this post Link to post Share on other sites

gooooog 10 Posted October 9, 2011 im using it for a restaurant im designing for my uni project. how do I get hold of a path or can i import that picture somehow? thanks Quote Share this post Link to post Share on other sites
JD Mather 12 Posted October 9, 2011 ...how do I get hold of a path 3dpolyline You could import your picture, but I don't know what good that would do. Attach here what you have completed so far if you can't figure it out. Quote Share this post Link to post Share on other sites
gooooog 10 Posted October 9, 2011 they cannot be converted into surfaces for some reason i dont know whats goin on thanks paraboloide.dwg Quote Share this post Link to post Share on other sites
JD Mather 12 Posted October 9, 2011 You are doing too much work - you only need the 4 boundary edges. Create using 3Dpoly with C (for close) as your last point. or you could use Loft with Guide curves, but I think I would simply use a closed 3dpoly and Patch. right click and select proper option that will allow you to select the 3Dpoly boundary) Quote Share this post Link to post Share on other sites
gooooog 10 Posted October 14, 2011 this really isnt working... i must be doing something wrong Quote Share this post Link to post Share on other sites
JD Mather 12 Posted October 14, 2011 this really isnt working... i must be doing something wrong Do the cube wire frame. start 3dpoly and click the boundary points (use C for close on last point) Do a Patch (check right mouse button options for proper selection).

SEANT 17 Posted October 15, 2011 For something like this I’d recommend using the Loft methodology – though I think 2 lines is enough (see attached). Patch is useful; though in this instance the resultant geometry is a trimmed surface. AutoCAD does not treat it as such, but the isolines suggest it – the Acis/Brep information confirms it. So, even if the surface is within tolerance, the Patch will not have traits associated with the doubly ruled hyperbolic paraboloid, nor a regular (fully contained) UV Parametrization.
