So ones you import STL format in ANSA it reads the elements, yet you can remesh the surfaces if need. STL files contain no scale information, and the units are arbitrary.) In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. Moreover, as it defined in Wiki (An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. STL files only stores meshed objects?įor STL, not just in ANSA but everywhere else it's by definition a mesh that contains distorted elements. Is it possible to "un-mesh" it in ANSA? 2. When exporting my geometry into STL file, some basic mesh is auto-generated. Hii, Your problems are fairly basic, so please find below a quick answer to your questions in RED. One must force a change in the underlying model to cause the tessellation to be recomputed - for example, by editing a sketch parameter (Setting it to its original value will suffice).Importing STL/STEP files, un-mesh? - CFD Online Discussion Forums In addition, exporting immediately after changing the display tessellation preference value will not have the desired effect because display tessellation is not updated immediately. However, because those parameters control the tessellation used to render shapes on the display, decreasing them will slow down display rendering, often significantly. When exporting from another workbench using File → Export., the tessellation is controlled by the overall display tessellation set in Edit → Preferences. In such cases you may need a finer tessellation value. If you are exporting to use in 3D-printing, this may result in an under-sized hole, for example. This results in slightly under-sized inside dimensions for curved surfaces. Curved surfaces are represented in STL as a series of straight-line segments, generated via tessellation.For example, you can fuse meshes before exporting.
