The Implement of Parametrization Drawing of CAD in Coal Preparation Plant

In accordance with the question of big workload of drawing and difficult found of gallery of faclity in CAD of coal preparation plant, this paper analyses the characteristics of the shape sameness and size unlikeness. Adoptting the parametrization drawing method, the drawing programmes of equipment using parameter are developed. The work is beneficial for improving the efficiency of drawing, reducing the workload of building warehouse, saving the EMS memoery.
