我将CSS应用于模型，之后我再也无法使用它，甚至无法渲染。现在，每当我尝试打开它时，我都会遇到以下异常：

“属性”视图现在只显示消息“属性不可用”，因此我无法删除CSS。有没有希望保存这个模型？
谢谢。
答案 0 :(得分：0)
这个问题是由CSS文件中的错误引起的。我定义了一些颜色：
@variables
{
myRed: #ff7777;
myCyan: #55ddff;
}
后来有了一个风格：
[appliedStereotypes~="Stereo"]
{
gradient: myRed vertical;
background-color: myCyand;
bold:true;
shadow:true;
elementIcon:true;
qualifiedNameDepth:full;
}
替换myCyand myCyan之后，模型再次成功运行。
不幸的是，模型中的元素没有被设置样式，但这是另一个问题。
