With the numbered paragraphs shown above, there is no extra spacing between the paragraphs. That’s easy to fix. Go ahead and type out at least part of your first numbered paragraph, then go to the Page Layout tab and adjust the value of Spacing After in the Paragraph section. Still no extra space? There’s one more setting to check. Click the launcher arrow in the lower right-hand corner to go to the Paragraph dialog box, uncheck the box next to “Don’t add space between paragraphs of the same style.” Click OK. That paragraph and all the remaining numbered ones will have more breathing room.
In this situation I would suggest using an Alternate Layout. Once the content is final, choose Create Alternate Layout from the Pages panel menu. Make sure to create the new layout the same size and orientation as the original and then use the Numbering and Section Options dialog to specify the numbering required for the second catalog. The Print dialog will then let you select which layout to print.

You will occasionally want to place an unnumbered paragraph in the middle of a sequence, but the moment you hit Enter, another paragraph number pops up. To fix this, toggle paragraph numbering off by pressing the paragraph numbering button you used for the previous paragraph. (If you use the button’s drop-down, choose None as the numbering scheme.) Unfortunately, the paragraph settings won’t revert to Normal here; it’ll usually have the paragraph indented 0.25. Use the keyboard shortcut CTRL+Q to strip paragraph settings out, then revise the formatting as you wish. numbering in coreldraw
