css - Papyrus:将 CSS 应用于模型后出现异常

Question

我将 CSS 应用于模型，之后我就无法再使用它了，它甚至没有得到渲染。现在每次我尝试打开它时都会出现以下异常:

Properties View 现在只显示消息“Properties are not available”，因此我无法删除 CSS。这个模型还有救的希望吗？

谢谢。

Answer 1

异常是由 CSS 文件中的错误引起的。我定义了几种颜色:

@variables 
{
    myRed: #ff7777;
    myCyan: #55ddff;
}

后来有一个风格:

[appliedStereotypes~="Stereo"]
{
    gradient: myRed vertical;
    background-color: myCyand;
    bold:true;
    shadow:true;
    elementIcon:true;
    qualifiedNameDepth:full;
}

将 myCyand 替换为 myCyan 后，该模型再次发挥作用。

不幸的是，模型中没有元素被设置样式，但这是另一个问题。
