+ | **Rough overview: Making a ply file for a projector** | ||
+ | |||
+ | - Obtain a 3D model of the ply, in the same coordinate system as the layup tool into which it will be projected. | ||
+ | - Create a boundary for that ply, in the form of a single polyline. | ||
+ | - Create a series of points spaced around the perimeter of that polyline, which will be projected by the laser. Note that these typically have to be created in the sequence (either all cw or ccw) that they will be projected. The spacing can vary, but 3" is typical. Always include a point in any corners that exist. | ||
+ | - Export the point data to a text file. | ||
+ | - At this point the instructions will vary somewhat depending upon the particular system you're using. In general: Create a " | ||
+ | - For multi-head projection systems, you must append each line of point data with a Surface Vector. This is used to determine which of the heads is " | ||
