Hi,
To successfully use the Flip Horizontal/Vertical option, ensure you select the element you wish to flip before accessing the flipping options. If the options are greyed out, it is likely because no element has been selected for flipping.
- Click first on the Home tab.
2. Click on the Select option (this button looks like a mouse cursor).
- After clicking on the option "Select", click on the object on your drawing that you want to Flip. After you click on this object it will become yellow.
- Click on the Effects tab.
- Click on the option Flip Horizontal.
