Changing floor on an image - part 2

Now create a new layer by click on New layer info, set it's name as floor guides and click Ok.

Set the layers order as shown on the image bellow by draggin down the floor guides layer.

Hide the Background copy layer by clicking on the eye icon to its left; unhide the Background layer and select the floor guides layer by clicking on it, so it will be our current working layer.

Select the Brush tool and set as follows:

Brush size - 3 pixels
Mode - Normal
Opacity - 100%
Flow - 100%
Airbrush - Unselected

Use again the Pen tool and draw some lines as shown in the picture bellow.

Try to draw this lines over the horizontal floor lines, so they could be useful as a good perspective guide.

No go to the Paths tab, right click on Work path and select Stroke path. On the new window select the Brush as the tool and be sure the Simulate pressure checkbox is unchecked.

Note: It's very important that you've setted the brush settings on step 6, since it's the tool we'll use to make the guides.

You've got the horizontal guide lines as shown on the image bellow, if don't, be sure to set the Brush parameters mentioned on step 6 and repeat the 7 and 8 steps.

Now it's time to create the vertcal guides:

1. Use the Pen tool to draw the guides, following the floor lines.
2. Stroke the path you've created.

Do this as you did on step 7 and 8 for the horizontal lines.

Note that we only need to draw some lines and I've drawn a line at the top right border of the floor area, this will give us a more accurate guide when applying the new floor.
