[Multi dynamic.skp](https://forums.sketchup.com/uploads/short-url/bL7Ljq161y4JOTuLk7f8SNy0wmc.skp) (143.0 KB) Dear all kindly helper, I don’t understand why I do the following step will get wrong… “Component A”: Animate(“Z”,0,10) “Component B”: Animate(“Z”,0,20) “Component C”: Animate(“Z”,0,30) “Component D”: Animate(“Z”,0,40) every animate of those single component works and in their right position. Then I group all together as a new Component “ABCD”. Then in onclick, I input: ANIMATE(“D!Z”,0,40); ANIMATE(“B!Z”,0,20); ANIMATE(“A!Z”,0,10); ANIMATE(“C!Z”,0,30) All get wrong position, 10 becomes 25.4, 20 becomes 50.8, etc… Am I doing anything wrong? The second questions is, when I already made animate of those single component Is there other way that I can just activate their “onclick” animate, something like, “A!onClick+B!onClick+C!onClick+D!onClick” Waiting for all your kindly reply. Thank you so much ---

Hi @icarus1005 , I’m not a my Sketchup computer right now but regarding your first point, from what you described, it looks like a unit issue because 2.54 cm = 1 inch. You should look at the unit of both parent and children and make sure they are both in cm. ---

Yes, there is a bug with conversion, text is always read as inches, so the onclick when used out of context of the level is not converted [Multi dynamic.skp](https://forums.sketchup.com/uploads/short-url/sxFxkbcn709IUa6d5dz85hLd6UG.skp) (165.7 KB) two examples, one to add conversion at parent level, other to set the 100cm at parent then have the z values reference that Other functions to be aware of the inch values are “CURRENT” and “FACEAREA” ---

当你需要更改组件尺寸时，出现了图形尺寸与实际不符，可进入组件内，将模型再一次创件组件，并将组件的坐标轴与当然组件设置一致，然后再将创建好的组件的尺寸、坐标的参数与与当前的组件设置一样，这样就可以解决。
