Autodesk Cfd Free Surface

[Justina Ky]

Iown a Surface Pro 6 with I7 and 16gb of Ram. At the last company I worked at, I had a single user license. I ran Revit (2018-2021) on that surface device all the time with little or no issue. It even has the better variant of the onboard video but can't remember what it is.

KeySurfaceFix runs inside Autodesk Civil 3D and allows you to scan surface models within the current drawing for holes and fill these by adding a point, based on the average surrounding values so that your surface longer has holes and more accurately reflects the existing site or your design proposals.

Cool program for big surfaces: each hole can be viewed. But it's better to fix it manually, because the elevations of points created by the program in holes are not interpolated, but equated to any nearest one, which can greatly affect the quality of such a surface. Great idea, you need to modify the code by interpolation!

A recently granted patent (Publication Number: US11928391B2) outlines a method for computer-aided design programs to generate and modify subdivision surface models efficiently. The method involves creating a subdivision surface model with a topological control structure and stored NURBS surfaces representing the limit surface. Users can perform direct edits on the NURBS surfaces using a NURBS modeling tool, leading to modified NURBS surfaces. The program then associates geometric modifications with these edits and allows for further modifications to the control mesh of the model. The updated limit surface is obtained from the modified control mesh, and the program tracks and updates the modified NURBS surfaces accordingly. The method also includes processing the stored NURBS surfaces for output by physical devices such as display devices, permanent storage devices, digital projectors, or computer-controlled manufacturing systems like additive or subtractive manufacturing machines.

Furthermore, the patent describes a system that includes a non-transitory storage medium with instructions for a computer-aided design program and data processing apparatus to execute the operations specified in the program. This system enables the generation, modification, and output processing of subdivision surface models efficiently. It also allows for the creation of toolpath specifications for manufacturing systems based on the stored NURBS surfaces. The system's capabilities extend to handling geometric modifications, tracking relationships between surfaces, and updating NURBS surfaces based on user edits. Overall, the patented method and system offer a comprehensive solution for designing and manipulating subdivision surface models with NURBS surfaces, catering to various output requirements for physical devices and manufacturing systems.
