Layout / 67
To separate all overlapping regions, choose
Separate Regions from the Format menu. Wherever regions overlap, this command moves the regions in such a way as to avoid overlaps.
Note Be careful with the Separate Regions command since moving regions may change the order of calculation. You can also drag regions individually, add lines by pressing [Enter], or cut and paste the regions so they don’t overlap.
Highlighting Regions
You can make certain regions stand out by highlighting them with a colored background:
1.Click in a region or select multiple regions.
2.Choose Properties from the Format menu.
3.Click the Display tab.
4.Check “Highlight Region.” Click “Choose Color” to choose a highlight color other than the default choice.
Mathcad colors the background of the region.
Changing the Worksheet Background Color
To change the color of the background of your entire worksheet:
1.Choose Color from the Format menu.
2.Choose Background to see the colors you may choose from.
Layout
Before printing a worksheet, you may want to adjust the margins, paper options, page breaks, and headers and footers.
Setting Margins, Paper Size, Source, and Orientation
Mathcad worksheets have user-specifiable margins at the left, right, top, and bottom of the worksheet. To set these margins, choose Page Setup from the File menu.
Use the four text boxes in the lower right of the Page Setup dialog to specify the distances from the margin to the corresponding edge of the actual sheet of paper.
You can also use Page Setup settings to change the size, source, or orientation of the paper. See “Printing” on page 74 for more about printing your Mathcad worksheets.
68 / Chapter 7 Mathcad Worksheets
Tip To use the margin and other page setup settings from the current worksheet in new worksheets, save the worksheet as a template as described in “Creating a New Mathcad Template” on page 62.
Page Breaks
Mathcad provides two kinds of page breaks:
•Soft page breaks. Mathcad uses your default printer settings and your top and bottom margins to insert these page breaks automatically. You can see these dotted horizontal lines as you scroll down in your worksheet. You cannot add or remove soft page breaks.
•Hard page breaks. You can insert a hard page break by placing the cursor and choosing Page Break from the Insert menu. Hard page breaks display as solid horizontal lines in your worksheets.
To move or delete a hard page break:
1.Drag-select the hard page break as you would select any other region in your Mathcad worksheet. A dashed selection box appears around the page break.
2.Choose Delete from the Edit menu or press the [Delete] key.
3.To move the page break, just drag it to a new position, or delete and reenter.
Tip Any region that overlaps a soft or hard page break prints by default in pieces on successive pages. To separate a region from a hard page break, choose Separate Regions from the Format menu. However, this command does not separate regions from overlapping soft page breaks. Choose Repaginate Now from the Format menu to force Mathcad to move soft page breaks above any region that would print in pieces on successive pages.
Headers and Footers
To add or modify headers or footers choose Header and Footer from the View menu.
