Scaling a Drawing

TPC provides very flexible drawing scaling. Use the Zoom Extents command to have TPC compute a scale for you. Then as you develop the drawing, re-scale it as needed. Because TPC retains the text sizes as you re-scale, you’ll never have to go back and re-size the text like you would in CAD.

The Zoom Extents Command

Zoom Extents command computes the coordinate extents of the survey plus any survey space objects you may have added to the drawing, and scales the drawing so that they all fit on one page.

The easiest way to scale the drawing is from the scale pulldown in the Drawing View toolbar. Just expand the list of scales and select the one you want. The currently selected scale is always displayed on the Format toolbar, so it’s easy to tell where you are.

When you select a scale, Drawing View redraws the survey at the new scale using the current position of the drawing on the page. The current scale is also shown on the status bar at the bottom of the screen next to the X/Y cursor coordinates.

Window Extents Command

The window extents command allows you to choose the extents of the drawing to which you will apply the scale.

Displaying the Scale Pulldown List

TPC displays the current drawing scale in the Scale pulldown list in the Drawing View toolbar. The current drawing scale is always displayed, but you can easily select a new scale by expanding the pulldown list and selecting the scale you want.

If you do not see the Scale pulldown or the Drawing View toolbar

Choose View | Customize View
Left click the Toolbars tab
From the list of Toolbars, make sure Drawing View is checked
Choose Ok

Determining the Drawing Scale

To determine the current drawing scale do any one of the following

Look at the list of drawing scales in the Drawing View toolbar. The current scale is always displayed here.
Look at the scale entry in any of TPC's predefined title blocks.
Look at the scale displayed in any of TPC's predefined scale bars.
Choose Tools | Drawing Settings and select the Miscelaneous tab.

Setting the Drawing Scale

Look at the list of drawing scales in the Drawing View toolbar. The current scale is always displayed here.
Select the scale you want from the scale list
Enter the scale you want in the scale list. Use this method to enter scales that are not predefined in the list. The scale you enter will not be permenantly added to the list.
Choose Tools | Drawing Settings and select the Miscelaneous tab. Enter the drawing scale here.

Editing the Scale List

If you would like to use a scale that is not listed on the Format toolbar, choose Tools | Scale List... and enter the scale you want. The Drawing View toolbar will display the closest scale it has to the scale you enter here, but the drawing will be at the entered scale.

Automatic Scaling

When you enter data in a Traverse View that is not sharing the current drawing, TPC displays the traverse in the Drawing View, rescaling it as needed to fit on the page. It’s as if you choose View | Zoom | Zoom Extents after entering each point.
