Hello! I'm afraid the translation is failing us, I don't understand quite well the question.
could you please describe better and provide examples of what you mean?

你好！ 我担心翻译失败了，我不太清楚这个问题。
你能不能更好地描述并提供你的意思的例子？

If you mean how to create a clipping attachment with perfectly straight edges, we don't currently provide tools to do that. You could export to JSON, adjust the values of the clipping attachment vertices, then use Import Data to bring it back into Spine. Some users do this to create a perfectly square 100x100 clipping attachment, then they translate or scale the vertices to get the actual size they want.
如果您的意思是如何创建具有完美直边的剪裁附件，我们目前不提供这样做的工具。 您可以导出到JSON，调整剪裁附件顶点的值，然后使用“导入数据”将其重新带回Spine。 一些用户这样做是为了创建一个完美的正方形100x100剪裁附件，然后他们翻译或缩放顶点以获得他们想要的实际尺寸。
