ubuntu下安装freeCAD支持DWG格式

Why Can't I Import DWG Files into FreeCAD?

The DWG format is a closed source binary file format that is not directly supported by FreeCAD. It requires an external 3rd party file converter to first convert then import the conversion into FreeCAD for use.

What Do I Need To Be Able To Import DWG Files?

Teigha Converter

• homepage: http://www.opendesign.com/guestfiles/TeighaFileConverter
• license: freeware
• optional, used to enable import and export of DWG files

The Teigha Converter is a small freely available utility that allows to convert between several versions of DWG and DXF files. FreeCAD can use it to offer DWG import and export, by converting DWG files to the DXF format under the hood,then using its standard DXF importer to import the file contents. The restrictions of the DXF importer apply.

Installation

On all platforms, only by installing the appropriate package from http://www.opendesign.com/guestfiles/TeighaFileConverter . After installation, if the utility is not found automatically by FreeCAD, you might need to set the path to the converter executable manually.Change workbench to "Draft", than in the menu Edit -> Preferences -> Import/Export -> DWG and fill "Path to Teigha File Converter" appropriately.

大概意思是说下一个第三方转换格式的插件，并在FreeCAD中导入。
