如何通过 Catia 中的 API 控制 3D 模型 [英] How to control a 3D model via the API in Catia

问题描述

我有以下场景:我正在使用一些柔性传感器、arduino 板和 5 个伺服器构建一个电子动画手.这方面没有问题.但我有以下想法:在 Catia 中构建手的 3D CAD 模型，并实时创建虚拟手以实时复制真手的动作.当我用来自某个传感器的一些数据实时绘制一些图时，我在 Matlab 中使用了一些东西.可以在 Catia 中做到这一点吗?从 arduino 获取数据并基于该数据实时模拟虚拟手的运动.你能告诉它是否可能吗?

I have the following scenario: i am building a animatronic hand using some flex sensor, arduino board and 5 servo. No problem on this side. But i have the following idea: to build a 3D CAD model of the hand in Catia, and in real time the virtual hand to copy the movements of the real hand in real time. I used something in Matlab when i did some plots in real time with some data from some sensor. It is posible to do that in Catia? To get the data from arduino and based on that data to simulate the movements of the virtual hand in real time. Can you tell if it posibile ?

手部的 3D 模型不会很复杂，手部也不会移动得很快.

The 3D model of the hand will not be very complex and the hand won't move very quickly.

推荐答案

恐怕还不够快.也许使用简化模型会有所帮助.

I am afraid it would not be fast enough. Maybe using a reduced model would help.

然而，最好的选择是拥有一个与 CATIA 和 Arduino 板通信的 VB.NET 应用程序(我认为 C# 也可以工作，但从未尝试过).

However, the best option is to have a VB.NET application (I think C# would also work, but never tried it) that communicates with CATIA and Arduino board.

要从 VB.NET 获取 CATIA，您可以执行类似操作

To get CATIA from VB.NET you can do something like

Module Main
    Sub Main()
        Dim CATApp as System.Type = System.Type.GetTypeFromProgID("Catia.Application")
        Dim CATIA as Object = System.Activator.CreateInstance(CATApp)
        'use CATIA object from now on as you would usually do
    End Sub
End Module

要与 Arduino 板通信，您需要监控 串口

To talk with the Arduino board you need to monitor the Serial Port

现在您可以从 Arduino 读取数据，对其进行处理，并使用自动化 API 向 CATIA 发送命令以更新您的模型.

Now you can read data from Arduino, process it, and send command using the automation API to CATIA in order to update your model.
