Make Solid From Points By Poisson

This command creates a solid model from a collection of x,y,z points by using the Poisson method. The points need to cover all sides of the surface (top, bottom, left, right, front, back). The Poisson method 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. Since the input for this routine uses points in the drawing, the difficulty of CAD to handle a very large number of points limits the number of points this routine can process. This function is also available in the Point Clouds module which stores the data outside of CAD and can process more input points.

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.

Tolerance: Indicates how much noise is expected in the point data. This setting helps remove outlier points. If the resulting surface is too spikey, adjust this value higher.
Precision: Controls pre-processing calculations. A smaller value results in a tighter solid.
Range: Controls how far the model looks for connecting points. If the solid does not span over expected gap areas, raise this value higher. If the solid spans over unexpected areas, lower the value. 
Tightness: Controls the density of the triangles. The higher the value, the smaller the triangles of the resulting solid.
Report Residuals: Reports the residual distances between the source points and the solid model.
Draw Projection Lines: Draws lines from the source points to the solid model.
