Research and Application of Parametric Design in Traditional Plug-Flow Aeration Tank with Drawing Methods

Abstract

By using the technology of CAD drawing and standard design calculation is very necessary and feasible. Designers can use the technology of parametric drawing, carries on two times of CAD development of the use of VBA language, the water processing graphics processing and engineering graphics rendering and completed in the computer, realize the parametric design of water treatment structures. Users only need to input the basic parameters that can be completed treatment structure graphics and rendering in CAD, reduce the processing procedure and time complexity. Based on the traditional plug flow aeration tank as an example, introduces the parametric design of traditional plug flow aeration tank by VBA.

Research on the Parametric Data Acquisition Technology for Rural Real Estate Fieldwork

“…After completing all annotations, field operation data acquisition will end. Automatically update house dimension chain after inputting dimension driven drawing dimension data and realizing dimension driven drawing [12]. Algorithm flow is as follows (taking horizontal dimension chain as an example): ① As shown in Figure 9…”
