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(yōu)化工作流的過程中，頻繁修改代碼，有什么辦法避免呢？

環(huán)境配置

安裝mimics20.0后，

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

使用python官網(wǎng)的3.5.2 x64版本覆蓋安裝，勾選安裝pip和添加環(huán)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(jī)工具命令提示符執(zhí)行pip3 install pyqt，為mimics內(nèi)嵌的python加入pyqt。

UI設(shè)計(jì)

使用qtcreator編輯設(shè)計(jì)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(dǎo)板需要重復(fù)操作的部分轉(zhuǎn)化為代碼，有些使用for循環(huán)順序操作，有些將之順序列出，逐條執(zhí)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(biāo)間距離計(jì)算、方向、位移、延申函數(shù)

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(zhuǎn)化后的代碼

優(yōu)化工作流

通過本文提出的方法可以減少設(shè)計(jì)中的固定操作，將需要多次鼠標(biāo)點(diǎn)擊才能完成的操作優(yōu)化為單次點(diǎn)擊即可完成，減少重復(fù)勞動(dòng)，提高效率。優(yōu)化3D打印導(dǎo)板的設(shè)計(jì)過程：從一個(gè)團(tuán)隊(duì)數(shù)天時(shí)間，縮減到一個(gè)人數(shù)小時(shí)。
