HOW TO DO CONTOURING INTO AUTOCAD CIVIL 3D 2013 SOFTWARE
The VisCAM and SolidView software packages use the two "attribute byte count" bytes at the end of every triangle to store a 15-bit RGB color:.There are at least two non-standard variations on the binary STL format for adding color information: įloating-point numbers are represented as IEEE floating-point numbers and are assumed to be little-endian, although this is not stated in documentation. After these follows a 2-byte ("short") unsigned integer that is the "attribute byte count" – in the standard format, this should be zero because most software does not understand anything else. The file simply ends after the last triangle.Įach triangle is described by twelve 32-bit floating-point numbers: three for the normal and then three for the X/Y/Z coordinate of each vertex – just as with the ASCII version of STL. Following that is data describing each triangle in turn. Following the header is a 4-byte little-endian unsigned integer indicating the number of triangular facets in the file. A binary STL file has an 80-character header (which is generally ignored, but should never begin with "solid" because that may lead some software to assume that this is an ASCII STL file). Binary STL īecause ASCII STL files can be very large, a binary version of STL exists. The spaces between "facet" and "normal" and between "outer" and "loop" are required. White space (spaces, tabs, newlines) may be used anywhere in the file except within numbers or words. In practice, however, all facets are simple triangles.

The structure of the format suggests that other possibilities exist (e.g., facets with more than one "loop", or loops with more than three vertices). STL files contain no scale information, and the units are arbitrary. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. 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. Binary files are more common, since they are more compact. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. This file format is supported by many other software packages it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL has several backronyms such as "Standard Triangle Language" and "Standard Tessellation Language". The report is now available on the Autodesk App Store.STL is a file format native to the stereolithography CAD software created by 3D Systems. Grade – Surface Feature Settings > Grade/Slope The precision of the numbers is taken from the settings of the drawing.Ĭontour – Surface Commands Settings > Add Contour Labeling Settings > Elevation The table can then be exported to a csv file if needed in another format. After selecting a surface the user is prompted to select a point to place an AutoCAD table. The report is installed into the Toolbox, and the user executes the Average Slope Calculation. The report utilizes the formula in the above picture. So to fix this deficiency I’ve created a report to perform the calculation for you.

Unfortunately Civil 3D doesn’t have a way to calculate the Average Slope of a surface based on contour lengths. It seems like using triangles would be best, but sometimes they want to use contours.

I’m not quite sure why, but planners tend to come up with interesting ways to calculate the average slope of a site.
