How to change dimensions of existing rectangle in Sketchup ?

To change the dimensions of an existing rectangle in SketchUp, you can use the Push/Pull Tool, the Scale Tool, or direct edits depending on whether the rectangle is part of a group/component or free geometry. Here’s how:

For Free Geometry:

1. Select the Rectangle:
   • Use the Select Tool (spacebar) to click on the face or edges of the rectangle.
2. Resize by Moving Edges:
   • Choose the Move Tool (shortcut: M).
   • Hover over one of the rectangle’s edges until it highlights, then click to grab it.
   • Move the edge to resize the rectangle. Enter the exact dimensions if needed (e.g., 2', 3' for feet, or 100mm, 150mm for millimeters).

Using the Scale Tool:

1. Select the Rectangle:
   • Use the Select Tool to highlight the rectangle’s face.
   • Ensure it’s not part of a group or component, or edit the group/component first.
2. Activate the Scale Tool:
   • Press S for the Scale Tool.
   • Click the rectangle to activate the scale handles.
3. Resize Proportionally or Along One Axis:
   • Drag the corner handle for proportional resizing.
   • Drag the middle edge handles to resize along one axis.
   • To set specific dimensions, type them into the measurements box, followed by Enter.

Editing Exact Dimensions:

1. Use the Entity Info Panel:
   • Select the rectangle’s face.
   • Open the Entity Info Panel (from the Window menu).
   • Adjust the length or width values directly, if available.
2. Redraw with Specific Dimensions:
   • If exact resizing isn’t feasible, erase the rectangle and redraw it:
     • Select the Rectangle Tool (shortcut: R).
     • Click to start drawing, then type the dimensions (e.g., 10', 5') and press Enter.

Editing Grouped or Component Rectangles:

1. Double-Click to Edit:
   • If the rectangle is part of a group or component, double-click it to enter edit mode.
2. Follow the Above Steps:
   • Use the Move Tool or Scale Tool as described above.
3. Exit the Edit Mode:
   • Click outside the group or component to finish.

By combining these tools, you can modify the rectangle to meet your precise requirements.
