Slope Analysis

This command allows you to inspect the slope of a mesh or a point cloud. An inspection value will be associated to each point of the cloud or vertex according to the angle between the local normal of the surface and the horizontal.

1. Without selection:

   1. Give a seed point to extract a "planar" part that you want to analyze.

   2. Adjust the extraction Tolerance.

   3. Click Validate to confirm the selection.

2. With Selection (or after step 1c):

   1. Define the Maximum slope tolerance to be respected, as well as the unit.

   2. With a point cloud: you can change the slider for the Local Normal Smoothing. This slider allows you to increase or decrease the radius of the influence zone on a cloud, in order to not see the slope from one point to the other, but measure the slope more globally on the cloud.

   3. Optionally, if a mesh has been selected, check Compute gridded inspection to compute a grid of inspected points in addition to the inspected mesh.
      

      1. Define the Horizontal axis of the grid (Z must be 0).

      2. Define a point to Pass through.

      3. Define the Horizontal step of the grid (ie along the Horizontal axis).

      4. Define the Vertical step.

      5. Optionally, after the preview, export the points directly to CAD:

         1. Set the texts height in model space.

         2. Export to DXF or Send To.
