mxcadviewer An Open-Source 2D/3D Graphics Viewer

👓 Feature Overview

• mxcadviewer supports viewing 2D files in formats such as DWG, DXF, and MXWEB, as well as 3D files in formats including STEP, IGES, and STL.
• Supports the recently opened files history viewing function.
• The 2D viewing module supports layer management, allowing users to add, delete, modify, query, and copy annotations. It also supports undo and redo operations for annotations, along with a text search feature.
• The 2D viewing module comes with a variety of commonly used annotation objects, including single-line text, multi-line text, lines, rectangles, ellipses, clouds, and leaders. It also supports multiple general measurement annotation objects, covering aligned dimensioning, linear dimensioning, area dimensioning, coordinate dimensioning, arc length dimensioning, point-to-line distance measurement, continuous measurement, batch measurement, side area calculation, area offset, radius measurement, and angle measurement. In addition, it provides table extraction and text extraction functions.
• The 3D viewing module supports functions such as section planes, part explosion, geometric measurement, display mode switching, and view projection mode switching.
• The entire project is developed in C++, based on the Qt framework and OpenCASCADE technology stack.

🔨 Build Guide

Dependencies

Install the following tools in advance:

• Git for Windows
• CMake
• Visual Studio 2017

Prepare the following dependent libraries:

• Qt ≥ 5.14 Note: Qt5 versions only are supported
• OpenCascade 7.7.0
• It is recommended to obtain precompiled third-party libraries from Download Link: 3rdparty.7z
• The mxcadlib library, available for download from Download Link: mx.7z

Preparations

1. Pull the latest source code of mxcadviewer from GitHub:

   git clone https://github.com/mxcad/mxcadviewer-cpp.git
   cd mxcadviewer-cpp

2. Read mxcadviewer-cpp/3rdparty/download_address.txt to download and extract the third-party libraries
3. Read mxcadviewer-cpp/mx/code/download_address.txt to download and extract the mxcadlib library

CMake Configuration and Project Generation

1. Create a new build directory under the mxcadviewer-cpp directory for building the program
2. It is recommended to use the cmake-gui graphical tool for configuration. Since the third-party libraries and mxcadlib library have been downloaded and extracted in the previous steps, CMake will automatically search for library files in the paths mxcadviewer-cpp/3rdparty/ and mxcadviewer-cpp/mx/code/ during initial configuration. Therefore, only the Qt5 path needs to be configured.
3. After setting the source path and build path in cmake-gui, click the Configure button, select the generator type as VS2017 x64, and then click Finish
4. If prompted that the Qt5_DIR variable is not set, configure the corresponding Qt library path for Qt5_DIR and click Configure again to complete the configuration
5. Click Generate to generate Visual Studio 2017 project files You can then open the project in Visual Studio 2017 for compilation and execution.
