Problem about creating the Multi mesh brush

[system]

I am having problem when creating the insert multi mesh,

it works well on plane, but it will crash into the geometry when it go across beveled edge or spherical objects.
I had try the depth setting but depth setting just simply lift up the whole curve.

Is it the problem of the source geometry of the IMM?

And how could I solve this problem?

Reduce the number of curvesteps in the stroke-curve-curvestep slider
This will allow to keep the same thickness of the geometry but have more subdivisions in the line, that is what is creating the problem.
