Line art

Hi
I want to render my image with Linart, I have grease pencil Addon also. It works perfectly in my files, but whenever I open the project from my colleague, it’s not working.
Can anybody help?

We’re going to need a lot more information than “it’s not working.”

I mean Line Art is not working
I am an Archviz Visualizer, All these days I was doing in 3ds max, Recently I shifted to Blender.
in 3ds max - Vray, there is an option to render in one colour with Vray toon. Same I am trying in Blender with Lineart.
But it’s not working as perfectly as I want.
The problem usually comes when I try to render a file from my colleagues. No lines comes on edges

So… he is using some addon you do not have ?? Because if he is not using any bigger version than you there shouldn’t be any problem…

There are several methods to get “line art”… like for example mentioned here:

You may have to elaborate this to get a more suited answer.

Thank you for reply
