Build A Round Hole Feature

The ROUNDHOLE sample program demonstrates how to create a STEP round hole feature. This program builds a sample product and then attaches a round hole feature to it. The program just creates the parametric description for the feature (circular profile swept along a linear path) and gives it a flat bottom condition.

We do not have any CAD geometry in this example, but the code also shows how to associate a feature with advanced_face instances on the product geometry.

"roundhole_out.stp" contains the sample output from this program.

This program creates the data set and saves it as a STEP Part 21 file called "output_file.stp". This is a text file, so you can look at it with a text editor or the STEP Part 21 file browser to see how the information is represented.

This sample program is available for the STEP Application protocols with feature definitions: AP219, AP224, AP238, and AP240.

Build Instructions

In the list above, select your Visual Studio version or platform, then right click on the link to save the zipped project files to your local disk. Unpack the zipfile.

On Windows, open the enclosed project file with Visual Studio and compile the program by selecting "Build All". The project creates a Console application that you can run from the command line. When using the 64bit version of ST-Developer, change the platform from "win32" to "X64" in the Visual Studio Configuration Manager before building.

On MacOS, Linux, and other Unix systems, the project directory contains a makefile that builds the sample program. The makefile uses the ROSE, ROSE_INCLUDE, and ROSE_LIB environment variables described in the ST-Developer installation notes. Compile the program by typing "make".

The Windows projects also include a makefile that you can use by typing "nmake", but you must run vcvars32.bat (found in the Visual Studio C++ bin directory) to make sure that the C++ compiler is in the command line search path.
