Scissor Mechanism, best way to model

Hi everyone,

I was recently faced with the task to model little grabbing tools. I managed to make it work but it took a lot of manual tweaking I ended up just eyeballing most of it and had to start over 4-5 times until i was satisfied with the result. I would love to hear if you guys can think of better ways to model this. See the reference image below:

If the grabbing tool is closed the lines above and under the tool are straight. As this tool is quite shiny its important to find a consistent way to get these lines as clean and straight as possible as the reflections are going to look off quite quickly as soon as the topology starts to be off :grin:

it looks like there are 2 symmetrical parts, this is the basic shape:

1

Once link-duplicated, flipped on the Z and Y axis and reworked it gives that:

2

Thank you for your reply! :smile:
Very similar to what I ended up with. Did you end up applying the mirror modifier and deleting the other 2 instances? This is what I did and I wonder if there is a way to only keep the Z and Y mirrored object without applying the modifier first

I didn’t use a Mirror, I created the basic shape, then link-duplicated it, flipped the copy, and assembled the 2 pieces together. Then I gave the corrections so that it fits well (as it is a linked duplication, the changes you make on a piece also happen on the other one). But yes Mirror would have done the trick.

I like your solution more! This way with (ALT-D) both sides are still edited if you decide to make small tweaks. (Just like an unapplied mirror modifier) How did you flip your linked object? Scale with a value of -1?

S Z -1 and S Y -1

Yes you can keep them linked as it looks like they are completely symmetrical, no need for a Mirror

Correct, thank you very much! :+1:

you’re welcome, it was a good exercice, I suffered as well :sweat_smile:
