In order to see the details of a drawing, you will often need to zoom in on part of it. Once you are zoomed in, you may need to pan the drawing (move part of the drawing out of the window so you can see another portion of the zoomed in drawing). Drawing View gives you several tools to help you pan and zoom.
When you zoom in on a portion of a drawing, you make the drawing objects larger by the zoom factor. A zoom factor of 2 would make the drawing objects twice as big as they actually are. A zoom factor of 1 would display drawing objects at their true or actual size.
Zooming does not change the drawing scale. The Zoom Page command for instance, shows the entire portion of the page inside the border in Drawing View. You will notice that the page zooms along with the drawing objects. As you zoom in, the page zooms beyond the Drawing View. You canít see it, unless you pan or scroll to it, but it is there.
When you print a drawing, TPC resets the zoom factor to 1.0 and regenerates the drawing for the printer or plotter. This gives you a true scale on the printout.
As you zoom in, Drawing View adds scroll bars to the drawing so that you can move to different portions of the drawing at the same zoom factor. Slide the horizontal or vertical scroll bars to pan horizontally and vertically.
You can also use the left mouse button to pan the drawing.
If you set your mouse wheel to the Zoom option, you can use your mouse for both panning and zooming.
You can use the Ctrl key to position the survey on the page. This is not the same as panning.
If you have a wheel mouse, you can use the wheel to zoom in and out in Drawing View.
Drawing View zooms in and out by about 10%. Hold down a Shift key and use the accelerator keys I for zoom in and O for zoom out to zoom twice as much.
The Zoom Page command zooms out until the whole page fits into the Drawing View window again. Use this to return to a known state after panning and zooming the drawing.
TPC keeps track of your most recent zooms, allowing you to zoom in to check something, then zoom back out to where you were.
Any one who has used a CAD program knows how frustrating it is to zoom in on a tangle of point descriptions only to see a larger tangle. This is a common problem when you have lots of survey shots close together. Your only option in CAD is to resize the text to figure out what is what, then possibly change it back later.
The Zoom Points command toggles the zoom factor of the point labels, line annotations and point symbols between 1.00 and the current zoom factor of the drawing. Now when you zoom in on a tight cluster of points, turn off zoom points and Drawing View will draw these entities using a zoom factor of 1.00, making them easier to read and work with.
When you print the drawing, the zoom factor is set to 1.0 and Zoom Points has no affect on the printed output. Zoom Points is also turned On when you choose the Zoom Page command.
The Zoom Extents command works differently from the other zoom commands in that it actually changes the scale and position of the survey on the drawing.
Zoom Extents computes the extents of the survey, then scales it to fit entirely on one page.
Automatically recomputes the drawing extents as you enter new points allowing you to see new survey points are you create them.
As you zoom in and out, TPC remembers the previous zoom settings. You can back up to any of the previous zooms by choosing View | Zoom | Zoom Previous.
When you open a Traverse View, TPC creates a temporary drawing in Drawing View to show the data in that traverse. When you close the Traverse View, TPC returns to your current drawing and picks up right where you left off with the zoom.
