你好！请问如图中Pointools中的颜色约束功能该怎么使用？
我想用这个功能对某一灰度的点云上颜色，比如只对图中标识线着色，但是试了几次都没有成功。

Hi Zey1,
This can work but you may find you get a better result if you set your Constraint to Intensity match instead of Colour.
Hi James,
I tried, but when I went back to the drawing page, it was still unconstrained.Is there any problems with my steps?
What is it that you are attempting to do? You appear to be in the paint command.
I want to color the traffic identification line by constraint.
Just color the id line.
