Make Solid From Points

This command creates a solid model from a collection of x,y,z points. The points need to cover all sides of the surface (top, bottom, left, right, front, back). The program prompts for CAD point entities in the drawing as the input for the model. Next the program has a dialog for the processing options.

The solid model is designed to follow the source points but does not exactly pass through each point. The options in the dialog control how well the model fits the points and has options for reviewing how well the model fits.

Octree Depth: Set maximum depth of the octree that will be used for surface reconstruction. When an octree node reaches the maximum depth, it will not split it to an internal node anymore. Default value is 8.
Points/Node: Controls minimum number of points should fall within an octree node as the octree construction is adapted to sampling density. Default value is 1.
Point Weight: Interpolation weight that point interpolation constraints are given when defining (screened) Poisson system. Its value specifies the important that interpolation of the point samples is given in the formulation of the screened Poisson equation. The results of the original (unscreened) Poisson Reconstruction can be obtained by setting this value to 0. Default value is 4.
Iteration: Controls how many times the program rebuilds the model. Each iteration should make the model fit the points better.
Generate Report: Reports the residual distances between the source points and the solid model.
Draw Projection: Draws lines from the source points to the solid model.
Draw Normal: Draws the calculated normals at each point.

Terminology
Octree: An octree is a tree data structure in which internal (non-leaf) node has eight children. Each child may be either another internal node (has another eight children) or a leaf (contains stored data items).
Screened Poisson Surface Reconstruction: It is a 3D surface reconstruction algorithm employed to rebuild 3D surfaces from point samples. The screened Poisson formulation considers all the points at once, without resorting to heuristic spatial partitioning or blending, and is therefore highly resilient to data noise.
