摘要
工程设计中多图联动建模技术提供用户友好的工程设计空间,建立了工程原理图和多个工程布置图之间的信息关联。采用3D数据存储——2D图形可视转换技术,得到图形变换矩阵。把设备的各个视图的图块预存入图形库中,绘图时,设置相应的绘图图层,只要在布置图的一个视图中插入设备图,系统会在其他视图中自动插入相应的投影图形,并且当修改或者删除一个视图中的图形时,其他视图对应的图形也会自动完成相应的操作,实现了多个工程视图的联动。
The user-friendly engineering design space is developed with the multi-view linkage modeling technique in engineering design.The projection relationship among drawings can be established simultaneously.The graphics transformation matrix can be obtained by 3D data storage and 2D visualization conversion technology.Firstly,put the blocks of the views into the equipment graphics lib.Secondly,set the drawing layer.Then,the linkage of multiple projection drawings is realized by inserting the equipment drawing into one of the layout views,the corresponding projection graphics will also be inserted in the other views automatically.In addition,if drawings are modified or deleted in a view,appropriate action will be completed in the other views automatically.
