Can't quad draw on certain polygons

[Anonymous]

I imported a simulated and flat surface from outside maya in a .obj format.

When I try to quad draw on other meshes, either created inside maya or imported from elsewhere, I have no issues in making the mesh live and then using quad draw to make poly-surfaces upon it.

But when I do the same with the imported meshes, I get a "minus" sign on it and it stops me from doing a quad draw on the mesh.

Here are the pics :

Basically, after putting the mesh on live mode, whenever I hover my quad draw tool on it there's a minus icon saying I can't quad draw on it.

What's causing this issue?

It's a bug on Marvelous Designer.

I changed the version and it worked again.
