deleteCell

Modify the damping mounts geometry by deleting two mounts located diagonally.

Import the geometry representing four damping mounts.

g = fegeometry("DampingMounts.stl")

g = 
  fegeometry with properties:

       NumCells: 4
       NumFaces: 16
       NumEdges: 16
    NumVertices: 16
       Vertices: [16×3 double]
           Mesh: []

Plot the imported geometry. The geometry has four cells: one cell representing each mount.

pdegplot(g)

Find the IDs of the cells containing the points with these coordinates: (50,250,50) and (1450,1200,50).

cellIDs = findCell(g,[50 250 50; 1450 1200 50])

cellIDs = 1×2

     2     3

Show the two points on the geometry plot.

pdegplot(g,FaceAlpha=0.3,CellLabels="on")
hold on
scatter3([50 1450],[250 1200],[50 50],"filled","red")

Delete the cells containing the points with the specified coordinates.

g = deleteCell(g,cellIDs)

g = 
  fegeometry with properties:

       NumCells: 2
       NumFaces: 8
       NumEdges: 8
    NumVertices: 8
       Vertices: [8×3 double]
           Mesh: []

Plot the resulting geometry.
