As a result, STL files contain no scale information, and the units are arbitrary. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. Binary files are more common since they are more compact.Īn STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. Solution: Direct the user’s attention to the Close Full Screen View button at the bottom of the window (depending on the version) or tell them to press Alt+V to display the View menu. The STL format specifies both ASCII and binary representations. ![]() STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing. Many other software packages support this file format. In this section, users can enable or disable each of the AutoFormat features they do not want to use. In the Word Options window, click the Proofing option in the left navigation pane. ![]() STL is a file format native to the stereolithography CAD software created by 3D Systems. Click the Options link in the left navigation pane.
