Pyqt魔改Mimics

你好！ 你是否想過，使用腳本來減少Mimics Innovation Suit 的很多繁瑣操作？但是在優化工作流的過程中，頻繁修改代碼，有什么辦法避免呢？

環境配置

安裝mimics20.0后，

找到scripting插件的默認路徑“C:\Program Files\Common Files\Materialise\Python\3.5.2”，

使用python官網的3.5.2 x64版本覆蓋安裝，勾選安裝pip和添加環境變量，以便在命令提示符cmd中，能找到python和pip3。

安裝Visual Studio 2015 Community version

使用vs2015 x64本機工具命令提示符執行pip3 install pyqt，為mimics內嵌的python加入pyqt。

UI設計

使用qtcreator編輯設計UI。
如還沒有qtcreator，在https://www.qt.io/下載安裝qtcreator。

代碼編寫

在mimics的Scripting Guide查閱mimics API，將制作導板需要重復操作的部分轉化為代碼，有些使用for循環順序操作，有些將之順序列出，逐條執行。

文件頭，需要引用的一些庫、定義

# Import the numpy library that is useful for some operations import numpy as np import math import sys from PyQt5 import QtCore, QtGui, QtWidgets from PyQt5.QtWidgets import QApplication, QDialog from PyQt5.QtCore import *# Define a shortcut md = mimics.data ma = mimics.analyze mi = mimics.indicate_coordinate guide_board_landmarks = ["AStart","AEnd","BStart","BEnd"]

坐標間距離計算、方向、位移、延申函數

def pp_length(a,b):x=a[0]-b[0]y=a[1]-b[1]z=a[2]-b[2]return math.sqrt(x*x+y*y+z*z)def pp_direction(a,b):l=pp_length(a,b)if l==0:return (0,0,0)x=(b[0]-a[0])/ly=(b[1]-a[1])/lz=(b[2]-a[2])/lreturn (x,y,z)def pp_add(a,b):x=a[0]+b[0]y=a[1]+b[1]z=a[2]+b[2]return (x,y,z)def pp_extend(a,b,l):d=pp_direction(a,b)return (b[0]+d[0]*l,b[1]+d[1]*l,b[2]+d[2]*l)

QT UI 轉化后的代碼

優化工作流

通過本文提出的方法可以減少設計中的固定操作，將需要多次鼠標點擊才能完成的操作優化為單次點擊即可完成，減少重復勞動，提高效率。優化3D打印導板的設計過程：從一個團隊數天時間，縮減到一個人數小時。
