Plan Preview

Shows a schematic plant. If you do not have two monitors (and I advise you to have) can use it to locate the section that is calculating.
You can change the zoom:

enhance
reduce
"Zoom Extents"
" Zoom Pan" by clicking the right mouse button or wheel and dragging.
Spinning the mouse wheel will zoom dynamic

Note: that the excerpts appear in a different color from the rest and you can click this plant to select a specific section:

If you click on this screen, the pipe closest to the click will be selected. Press and hold the CTRL button to select more than one pipe.

If you run your mouse over the pipe selected, you will see a line passing over the profile view, indicating the position and will also see the section gabaritada of Excavation for this section.

You can also change the colors of this screen. See parameters frame.
