![]() So the Gizmos are still available, even though you're in a 2D rendering mode.Ģ) The AutoCAD for 2013 manual's help page for DELOBJ states that its default value of 3 has the result that it "Removes all defining geometry for CONVTOSOLID, CONVTOSURFACE, CONVTONURBS, and CONVTOMESH commands." The CONVTOSURFACE help page states that it may be used to convert "Planar 3D faces" to Surface objects. E.g., 3DROTATE causes the 3D Rotate Gizmo to display for the duration of that command. They DO show up when you invoke a 3D command on a selection. at least not upon selection of an object. So far, the only drawback (to someone who is used to the 3D Wireframe environment) I have encountered is that the 3D Gizmos do not display. In this rendering mode, selection of my whole model is nearly instantaneous. The cure is to use 2D Wireframe rendering. It can take almost a minute just to select the whole model, and the process of swiping across the model is then interrupted by the cursor freezing and the little rainbow circle showing until the program catches up with your mouse cursor movement. For example, my model contains 36,482 facets. That may be fine for small models, but when the number of elements in the model increases greatly, it can dramatically sloooooooooow down interactions with AutoCAD. This note will offer some details to others who may be inclined to go in these directions.ġ) Since I tend to work in 3D, I have generally selected (3D) Wireframe as my rendering mode (upper left corner of the display area). Your instructions are generally correct, as usual. ![]() They are 3D Face objects, which can be converted to mesh with CONVTOMESH, but they resist MESHMERGE. I have attached a file that contains 2 of the 34,000+ triangles in my mesh. How can I get my data to become a valid cohesive mesh? Better than an explanation, I require a cure. Why AutoCAD deems my mesh objects to be "invalid" is not explained. (1) invalid object(s) removed from the selection set. Select adjacent mesh faces to merge:Specify opposite corner: 4 found ![]() Unfortunately, the MESHMERGE command fails. Afterwards, if I select any of the triangles, the Properties Inspector informs that they are indeed now "Mesh" objects. Two AutoCAD commands ought to convert this assemblage into a mesh. In AutoCAD, the data is displayed as if it were a cohesive mesh, but in actuality it is comprised of individual 3D Face objects. DXF file in Finder, and it opened in AutoCAD. I opened AutoCAD, then double-clicked on the. I imported the resulting file to MeshLab, which displayed the mesh perfectly, and exported it as a. The process seems to have the following flow chart:įilters > Texture > Parameterization: Trivial Per-Triangle > Parameterization: Flat Plane (instead of Filters > Texture > Parameterization: Trivial Per-Triangleĭoes anyone using meshlab can clarify a bit? I also have question, why the texture mapping from Parameterization: Trivial Per-Triangle does not reflect the image properly, it looks very random.AutoCAD could not create a mesh I need, so I wrote a program to create verticies and faces in the simple. It seems to make it (Parameterization: Flat Plane) work, before using Parameterization: Flat Plane, I’ve to use Parameterization: Trivial Per-Triangle. ![]() Filters > Texture > Parameterization: Trivial Per-Triangle.īut I cannot make Parameterization: Flat Plane (which I prefer) work using the following:Filters > Texture > Parameterization: Flat Plane My question, I can make Parameterization: Trivial Per-Triangle working if I just follow the procedure, i.e. Next, if I choose Parameterization: Flat Plane, texture mapping is smooth and it reflects the image. Now, if I choose Parameterization: Trivial Per-Triangle, the texture mapping does not properly reflect the image. Now the way I’m following is as follows:įilters > Texture > Parameterization: Trivial Per-Triangle or Parameterization: Flat Plane Hello, I’m trying to generate texture coordinates using meshlab for an obj model.
