Adds a planar solid primitive with the specified vertices. Planar solids offer a very convenient option to create custom, complex 3D geometries. You can find more information about planar solids in this page: Structures - Planar solid.

|---|---|
|
addplanarsolid; |
Adds an empty planar solid object. |
|
addplanarsolid(vtx, fct); |
Adds a planer solid object whose vertices are defined by 'vtx' and whose facets are defined by 'fct' |
Example
The example below adds a planar solid cut-face box using two methods. The first method uses the facet table as a cell array and the second method uses the facet table a matrix.
method_type = 1; # choose 1 or 2 to switch between methods
vtx = [0,0,0;
1,0,0;
1,1,0;
0,1,0;
0,0,2;
1,0,2;
1,1,2;
0,1,2]*1e-6;
# Method 1: facet table as cell array
a = cell(7);
for (i = 1:7) {
a{i} = cell(1);
}
a{1}{1} = [1,4,3,2];
a{2}{1} = [1,5,8,4];
a{3}{1} = [1,2,6,5];
a{4}{1} = [2,3,6];
a{5}{1} = [3,8,6];
a{6}{1} = [3,4,8];
a{7}{1} = [5,6,8];
if (method_type == 1) {
addplanarsolid(vtx,a);
}
# Method 2: facet table as matrix
b = matrix(4,1,7); # max four points per polygon, max 1 polygon per facet
for (i = 1:7) {
fpoly = a{i}{1};
for (j = 1:length(fpoly)) {
b(j,1,i) = fpoly(j);
}
}
if (method_type == 2) {
addplanarsolid;
set('vertices',vtx); # must be done first
set('facets',b);
}
