Because some things are supposed to be meshes, like models of people and animals.Are you avoiding a key BricsCAD performance tool?Īre you a BricsCAD user who favors using menus over using the keyboard for command input? If so, you might want to reconsider.
(A bit like comparing vector graphics with raster graphics). Whereas a mesh is just points joined by lines and faces. A solid is a mathematical entity governed by lengths and radii etc. So deviation from the expected sharp edge should give CAD the information needed to recreate the bevel in solid form. sorry I don't know the maths of splines (I don't use splines in my solids, I don't even know if i can turn a spine into a solid).īevels ? Bevels are always between two meeting surfaces. Oval ellipses (eg angular slice through a cylinder) also could be identified by their points from x, y, and z views. Then Once CAD has all the ellipses identified it would have to see what they were connected to. 60 degree ellipse in the z axis and 30 deg ellipse in the y axis means you have possibly the head of a cylinder bent up 30 degrees on its x axis. Of course it is quite processor intensive as CAD has to check the relationship of all points in a model from three angles and then identify if there are circles there. CAD has to identify entities and replace them.įortunately an elliptical solid leaves quite a distinct shape if viewed from all three planes. The main problem is elliptical and spline solids.īasically rather than stitch planes to make a solid. It is obviously more difficult than turning solids to meshes. There is a way to turn meshes back to solids. Hey BricsCAD developers, If you are there. The task is to make drawings, not to make solids (as much as I wanted them). Hopefully I'll have it posted by tomorrow)Ī customer send me a crate lid mold igs file that I had to make drawings for. I have posted it on a friends Youtube at (Sorry deleted link. There IS a way to get clean drawing if you absolutely must.
YOUTUBE BRICSCAD HOW TO
These meshes may be useful for other applications, but I don't understand how to use them with 2D views can be generated, but they also have so many facets that circles and arcs can't be snapped to or measured. It's very hard to select the right snap because of all the facets. I've tried this procedure many times on imported meshes and find the usual result of the EXPLODE, REGION, DMSTITCH, and DMSIMPLIFY commands is often a solid with so many triangular facets, it is not usable. We have the latest version of BricsCAD installed now (V18.2.14). So far point clouds are meant as sketch underlays to draw Inaccuracy in a plastered wall and what what is already a To convert these into more useful geometric objects.īasically the same problem with tolerances. That is something worked on also for things like point clouds Something which is much easier for a human brain and may beįaster by redrawing for CAD usage purposes. There would be needed an algorithm for all these many cases. Or row of arcs, with certain tolerances for angles betweenĮdges, that may be meant as a hard edge instead. Or checking if a row of edges may be described as a curve That could also be represented as a Solid.Īnd to determine if something may be meant as a circle,Īn algorithm would need to check the vertices positionsĪnd check if there may be a center point to which all vertices It is not easy to for a computer to detect if that is just aīunch of 3D polygons or should be a watertight volume Outwards will make that addition of connected faces You can't even have holes in a face, it's more like youīend a face around that hole to get the supportingĪ mesh volume is no real volume, just all faces pointing Once converted into an editable mesh a circle will getĪ simple Polygon with n vertices that define Faces and Like circles or boxes but that is just in their Tools. In a 3D Polygon App there may be some parametric These are just defined by their vertices. There is no parametric or intelligence in Meshes.
