我在将solidwo​rks中的模型xml​文件导入到simsc​ape中时模型中的r​evolute joint发生了报错，模型运动不了

报错如下：Revolute Joint 'Exo_assembly1/x02_1/Revolute2' has base and follower ports that are rigidly connected; it is ignored. Resolve this issue in order to simulate the model.

我检查了在solidworks中的模型连接，不是很理解这样的报错，请问应该如何解决呢？

这是一个机器人的关节，两边绿色的（0205右和0206左）是连接板，中间（0202）是关节的涡轮，他们的连接副很明显是转动副，但是0206和中间涡轮的连接没有报错，右边的0205却报错了，不是很明白原因，求指点

Hi @湉,

It seems you're encountering a rigid connection error in a Revolute Joint in Simscape after importing from SolidWorks. This issue is often caused by the way the CAD model is constructed. In particular, a joint in Simscape requires two separate bodies connected by a frame, but in some CAD models, joints may be added purely for assembly purposes without considering the dynamic behavior of the system.

This typically results from "bad" or overly rigid modeling practices in the CAD environment. To ensure a successful and repeatable import into Simscape, it's important to properly model the assembly in your CAD software with simulation requirements in mind.

In SolidWorks, it's especially useful to understand how mates map to Simscape joints. You can find more information here:

Improving the CAD model setup before import should resolve the issue.

Hope this helps!
