parasolid_frustrum

The goal of this project is to make it very easy to write C++ code that can read Parasolid text transmit files.

It does not implement any file writing, or graphical output. It also does not implement binary file reading.

What it does do is:

• provide a modern CMake interface
• read text transmit (x_t) files either from disk or from raw strings (useful for in-memory files)
• provides a basic Parasolid frustrum implementation to get started

Project Setup

Because Parasolid is a proprietary CAD kernel, you must have a Parasolid distribution available on your system in order to use this project. The location of your Parasolid distribution is expected to be set by an environmental variable $PARASOLID_BASE.

I recommend using CMake's FetchContent to use the frustrum in your projects:

include(FetchContent)
FetchContent_Declare(
  ps_frustrum
  GIT_REPOSITORY   https://github.com/deGravity/parasolid_frustrum.git
  GIT_TAG   v1.0
)

FetchContent_MakeAvailable(ps_frustrum)

...

target_link_libraries(my_target INTERFACE parasolid_frustrum)

This will fail if $PARASOLID_BASE is not defined.

$PARASOLID_BASE should be specific to your parasolid distribution, and is expected to contain the following files:

• parasolid_kernel.h
• kernel_interface.h
• frustrum_ifails.h
• frustrum_tokens.h
• pskernel_archive.lib

Using Parasolid

To use Parasolid in your C++ code, all you need to do is #include <parasolid.h>. This will give you access to the full Parasolid interface (from parasolid_kernel.h and kernel_interface.h), as well as the function ensure_parasolid_session(), which you must call at least once before attempting to use any Parasolid functions. There is no downside to calling this more than once.
