Write mesh to STL file



stlwrite(object,filename) writes the points and connectivity list of an antenna or array mesh to a STL file of specified name.

Create a rectangular shape. Divide the shape into two triangles. Extract the shape vertices to determine the vertices of the triangles. Define the points connectivity list and use the triangulation function on this list and vertices.

w = shape.Rectangle;
v = getShapeVertices(w)
v = 4×3

   -0.5000   -1.0000         0
    0.5000   -1.0000         0
    0.5000    1.0000         0
   -0.5000    1.0000         0

c = [1 2 4; 2 3 4]
c = 2×3

     1     2     4
     2     3     4

tr = triangulation(c,v(:,1),v(:,2))
tr = 
  triangulation with properties:

              Points: [4x2 double]
    ConnectivityList: [2x3 double]

Create an STL file from the triangulation object.


The software creates the customPlatform STL file. in your current folder. Use this file to create a platform object and visualize the platform.

plat = platform(FileName="customPlatForm.stl", Units="m")
plat = 
  platform with properties:

         FileName: "customPlatForm.stl"
            Units: "m"
    UseFileAsMesh: 0
             Tilt: 0
         TiltAxis: [1 0 0]
