convert a surface to a plane

[majedomaralfaraj]

hello everyone, 

I'm wondering if there's a way to convert a surface to a plane. because I use the floor generator plugin to make floors for my project and it requires the surface to be a plane. however making a plane to fit a room with irregular corners can be a headache or even not possible. so now I'm drawing a line along the walls of the room to get the shape and then extrude it 1cm but the floor generator plugin doesn't work  methwith thatod. so now I'm wondering if there's a to solve that.

thanks!

i don't use the floor generator plugin, you can convert the line with the extude modifer to a poly as you know won't the floor generator accept that

If you have a closed spline, adding an Edit Mesh modifier or a UVW Map modifier will convert it to a plane with no thickness.  Maybe that's what you need?

If this is the FloorGenerator from cg-source, you can use a spline as long as it is closed, no need to extrude it. So you can either draw a shape for the layout of your room, with snap on this should be fairly simple to do. Or grab the edges from the current walls/floor, and if Editable Mesh -> "Create Shape from Edges" ; if Editable Poly -> "Create Shapes From Selection". 

Edit: and like what Camedeck suggested, you have to use a single sided surface, it can't have thickness. So either from a shape, or detach the surface of a floor that is already there will get you there.
