Why can’t I enter dimensions to create precise rectangle in Sketchup?

If you’re unable to enter dimensions to create a precise rectangle in SketchUp, it could be due to a few common issues. Here are some troubleshooting tips to resolve this:

1. Incorrect Workflow for Entering Dimensions

• When using the Rectangle Tool:
  1. Click once to start the rectangle.
  2. Move the cursor in the general direction of where you want the rectangle to grow.
  3. Do not click again or press any other key—just type the dimensions directly.
     • Example: Type 10', 5' for a 10 feet by 5 feet rectangle, or 200mm, 100mm for metric units.
  4. Press Enter to confirm the dimensions.

2. Misunderstanding of Units

• Check your Model Units:
  • Go to Window > Model Info > Units.
  • Verify that your units are set correctly (e.g., inches, feet, millimeters, etc.).
  • If you’re entering dimensions without specifying units (e.g., typing 10, 5), SketchUp will use the default units set here.
  • To override, specify units explicitly (e.g., 10', 5' for feet or 200mm, 100mm for millimeters).

3. Typing in the Measurements Box

• In SketchUp, you don’t need to click on the Measurements (or Dimensions) box to type dimensions.
  • As long as you start typing after placing the first point, SketchUp will automatically accept input into the Measurements box.

4. Tool or Cursor Interference

• Accidental Clicks: If you accidentally click after starting the rectangle, SketchUp will assume you’ve finished drawing and won’t let you enter dimensions.
  • To fix this, undo (Ctrl+Z or Cmd+Z) and restart the rectangle.
• Other Tools Activated: Ensure that no other tool is interfering with the rectangle creation process.

5. Issue with Keyboard or Locale Settings

• Ensure your keyboard is working properly and that the comma (,) or semicolon (;) separator is correct for your locale.
  • For example:
    • US uses a comma (e.g., 10', 5').
    • Some European setups use a semicolon (e.g., 10'; 5').
  • Adjust your input format as per your system’s settings.

6. SketchUp Version or Bugs

• If you’re using an older version of SketchUp or a web-based version, occasional bugs can interfere with dimension input.
  • Update to the latest version of SketchUp to ensure compatibility.

Solution Summary

• Start the rectangle, type the dimensions directly (don’t click the Measurements box), and press Enter.
• Check your units in Model Info.
• Use the correct separator (comma or semicolon) for your locale.

If this still doesn’t work, restarting SketchUp or reinstalling the software might resolve any glitches.
