Lock aspect ratio

Hi

I have recently returned as a lucid chart user. I am quite certain it was possible to lock the aspect ratio of an object before. Now I don’t find that option anywhere. Does anybody know how to find it?

Thank you ​@kjell for the reply! I apologize for the delay here.

In the right-hand side panel, under Object, you can select the button shown in red below. That should allow you to lock the height and width ratio of a shape, to more evenly resize objects while keeping the aspect ratio locked. Would you mind trying this to see if this solves for what you’re hoping to see?

 

Please let me know if that’s not working as expected, or if you have any other questions. Happy to help!

Hi ​@kjell, thanks for posting in the Lucid Community!

You can lock the size of a shape without locking its location on the canvas using two different methods. 

 

Option 1: Right-clicking on a shape

  1. Right-click directly on the shape. 
  2. Hover over Lock/unlock.
  3. Select Lock size.

 

Option 2: Using the right side panel

  1. Select the shape you’d like to lock the size of. 
  2. You’ll see a menu bar above the shape. Select the button to Open right panel. 
  3. Once the right-hand panel has opened, select the tri-dot More button, located next to the lock symbol.
  4. Select Lock/unlock, and Lock size.

 

I hope this helps! Please let me know if you have any other questions, happy to help.

Hi

Thank you for the answer. This is also what I have now been doing. But if I remember correctly, there was earlier an option to lock the width/height ratio. It might not have been called aspect ratio. The idea is that I can then e.g. resize a circle easily without it becoming an oval.
