刚逛RPF发现一个老帖子,里面有段讲解如何调整比例,觉得很实用,就顺手分享给大家,不知道以前有没有人发过,也可能很多吧友都会吧,莫见怪~希望能对像我一样的新手有用~
Open a file in Designer, right click the 2D layout, select "measurement tool". Now you can point two points on the 3D view, the distance between them will be displayed.

This distance depends of the scale factor. To get a smaller helmet, decrease the scale factor. To get a larger helmet, increase it.
Here we have a helmet scaled at 1.648527 and 160.73mm from side to side.

If you want a 180mm wide helmet, just enter the suitable scale :
(1.648527/160.73)*180 = 1.84617

You can check : we get 180mm

Now the question is, "how do I know if it will fit my head".
And the answer obviously is : "measure your head!"
The trick I use :
