Designing a consumer product would require you to do curve projection at least one time unless you are in search of an overall shape. When you do a cutout of a panel/surface in order to insert a piece it is wise to fillet the edges of both pieces for rendering purposes so it ends up looking more convincing but sometimes you really need a bigger gap between two panels/surfaces. This is where some sort of gap tool creation would come in handy just to interactively expand or resize the existing gap when you do curve projection. So far one of the workarounds has been to do offset of the cutout which gives you a leeway to do proper bigger filleting of the edges to close the gap (that way it looks more pronounced in the render). I am not aware of any other workarounds cause I'm lazy to do some creative thinking.
I'm a relatively new user of Hypermesh v12.0 and have run into an issue when trying to use the 2D Automesh on a particular geometry. I am meshing an elliptical cylinder with interior stiffeners, i.e., frames, intercostals, etc. that are bolted together. I am modeling the vessel with 2D, first order elements and am modeling all fasteners and fastener holes. The problem that I run into is that the 2D automesher (including midsurface mesher) performs one of three operations: Failed surface mesh Meshes only around the holes (this is when I specify washers in the parameter/criteria files) Meshes over holes/cutouts that are below a certain diameter I've reworked and modified all parameters and criteria that I feel are relevant and even those that I feel are irrelevant. Further, when I perform topological cleanup and have the preprocessor locate and tag holes, it tags all holes except for those above a certain diameter (so Hypermesh is treating the larger and smaller cutouts differently). No matter what, I cannot mesh this structure and the direction that I feel I am taking now is non-intuitive and quite frankly arbitrary. Any guidance would be appreciated.
