  1. Hi guys, I've created an AutoLisp app which creates a cross section of the 3D terrain grid. The terrain can consists of raw AutoCAD entities: MESH / POLYFACE MESH / POLYGON MESH (one or more, even combined). As an author, I will be grateful for any comment, especially suggest...
  2. Hello people! Im using autocad 2018. I need to extract the frame lines from 3d meshes (i think its called a mesh but im not sure) I have attached an example file. Is there a way to automatically extract the outer lines so i could erase the rest and be left with only its fr...

    Drawing mesh (repeat squares)

    Hey... does someone have advice how to make a quick micro-scale mesh drawing in LT (so 2D)? It's gonna get complicated but I'll start with this XD

    Mesh to solid

    Helo, I have many mesh and need convert to solid 3D, the adjunt is a example. Any lisp, visual lisp for this. thank you. MESH TO SOLID.dwg
  5. Dear Friends, I need your help with the following case. I have a XYZ table which is coordinates and elevation. When plotted in 3D in Matlab or Excel, it results in a 3D surface plot which shows the topography of an area. My end goal is this: (1) create a solid object with these coordinates,...
  6. My grasp of auto cad(version 2004 here) is tenuous at best. I've attached two .dxf files. roof.dxf demonstrates what I am trying to create, roof panel 3d.dxf is what I actually need. From what I've gathered from reading and research that autocad won't "unroll' the shape so that I'll end up wit...
  7. Hello, I am using Matlab to create a surface I import into Autocad Mechanical 2015. Matlab uses a library to convert a matrix into a .dxf 3D surface. Depending on the option, the surface is either a cloud of points, or made of triangles or square patches (linking t...
  8. Hi. Is there a simple way to quickly draw a mesh out of the following splines created from a recent survey to represent a terrain. Note some data are missing. Thanks. Terrain.dwg

    Mesh to solid

    (please bear with me, this is my first post and I am very new to Autodesk products) Hello I need help with a project I am attempting to do on Inventor. I used Google Sketchup to create a model and realized that it needed to be in inventor- I exported the sketchup as an .stl and imported it into...
  10. Hello All, I am trying to create a 3D meshed surface from an irregular shaped solid I created using firstly a SPLINE, FILLET, PEDIT, and EXTRUDE. I have a solid in the basic shape now, but I am trying to create a meshed top and bottom (x, y, z,) to change the contours of those surfaces. Can anyon...

    2D polyline to a surface

    Hello All, I have created a series of splined lines into a polyline (pedit) which I want to extrude. When I extrude the polyline I only get an extruded polyline and not a surface. I need to create a mesh or make the surface a face to extrude to make a solid. I have not used AutoCad for some year...
  12. Hello guys, I am really new here. I need your help to make me understand what is the difference of editable mesh, poly, patch, and spline in 3ds max. I want to know when I have to use one of them and what kind objects can be convert to one of them? Thank you.

    Working with .stl files

    Hi I am working on a project where I am taking scans of the two pieces of a broken weld and trying to put them back together and I'm wondering if there is any program that can do this? Some more information, I welded two pieces of metal together and then broke the weld. I then scanned the two pi...
  14. Hey guys, Im doing a little graphic work (moonlighting) and was looking to create a jagged mountain-scape with triangular facets/faces (similiar to this image)... I was just wondering if you guys can please advise me the best method to creating such a mesh/surface/object. Most of my...
  15. Hello, there! For several days now I've been trying to lay a mesh on top of some contour lines. I've also tried the loft command, but with little success. I've tried several terrain plugins, but they all seem to misfunction because I have overlapping contours. Here is the dwg to get idea what I'...
  16. hello i was wondering if someone would help me out a little with t-spline? i have used t-spline simply to edit the edge faces of the geometry im currently working on, which is not meant to be very curvy at all... but once i have converted the meshed surfaces to t-spline, it seems impossible t...

    Refining a mesh

    Hi people My ANSYS-Computational-Fluid-Dynamics lecturer in the university has asked my class a question: "Why refining a mesh can improve the accuracy of a simulation" All the students have a day to think about this. I sort of know why this is happening but I like to have a super doop...
  18. Hi i've got to grips quite well with mesh modelling but i cannot seem to be able to mitigate this shape, a hyperbolic paraboloid in 3D Cad (see attached image)... can anyone give me any guidance on this matter? Thanks Clive
