DWG File Management Software With2-D And3-D Texts Editing Functions

As the domestic market was monopolized by foreign CAD softwares and they areexpensive and in order to solve the problem that text processing functions are justused on the2-D texts and we can’t preview the files before we open them in CADsoftwares,we design a "DWG file management software wiht2-D and3-D textsediting functions".We use Windows as the platform and Visual C++as the developtools to combine all kinds of knowledge.Finally make a software that we can use tomanage and preview the DWG files,edit the texts and edit the3-D texts in CATIA.The work contains: design and realize the interface of the software,realize theexplorer of the DWG files,research the DWG files and make the BMP as the previewpictures,pick out the BMP files and show them to preview the DWG files,realize thetexts inputting and editing functions after summing up the coding rules of texts inDWG and finally show them in DWG files,develop the3-D texts inputting and editingand previewing functions.In this article we explain the design and realization of the software,and confirmthe correctness and practical applicability by debugging and testing.
