a2s

The a2s command utilizes assimp to convert 3d mesh files to SketchUp files.

See here for a list of formats supported by assimp.

This is a basic converter which relies completely on the capabilities of assimp for the conversion. If assimp can not handle the conversion, no further attempt is made. Many formats result in poor or unexpected models. Textures are not imported for any format. Scale is fixed and set to a larger value to over-come SketchUp's "small geometry" limitation.

.stl, .ply, and .obj files generally convert well, which was the original goal of the code.

.dxf files do not typically convert well if at all. The exceptions appear to be dxf's exported using 3DFACE entities, and PolyFaceMesh variant of POLYLINE entiites.

Usage

On the command line...

> a2s input-file.ext

Creates a file named input-file.ext.skp in the same folder.

Download

See the Release page for the latest download. Unzip the files, then move them to a directory in your %PATH%.

Build Requirements

• cmake
• premake5 use cmake.
• SketchUp SDK
• A local clone of the assimp repository. assimp
• GNU g++ compiler tools, bin utils, and make for Windows. See Note.

Build Instructions

• set the ASSIMP_SRC variable in the build-assimp.bat file to your assimp source directory.
• run the build-assimp.bat file. This may take a few minutes.
• set the SKETCHUP_SDK and ASSIMP variable in the Makefile
• run make

Install

Once built, copy the a2s.exe file and the following 2 dll files to a folder on your %PATH%

• SketchUpAPI.dll
• SketchUpCommonPreferences.dll

Notes

I use scoop to maintain the required dev tools on Windows.

a2s defaults to using a SketchUp 8 file. Edit the main.cpp file if you want to change the default.
