FUSION 360 POLYGON SKETCH DIMENSION ISSUE

travisMCPYZ — Sun, 06 Feb 2022 18:33:20 GMT

Hello,

I'm trying to create a hexagon pattern on a sketch plane... I found this video on how to create it.

here's the video link

https://www.youtube.com/watch?v=mKQjvitMLjQ

This video is helpful, however after I create my hexagons and implement the sketch dimension between the two shapes, it causes the second hexagon to increase in size rather than just move to my specified distance.

before sketch dimension

after sketch dimension

how do I keep the hexagon size fixed for each shape so that when I apply the sketch dimension it just moves it rather than oversize it?

thanks for the help in advance!

Apply an equal constraint between a side of one hex to a side on the other hex.

I tried that and it gave me an error

Can you attach an f3d file of your model because if there was an equal constraint applied, then the hexes would be the same size.

I'd rather create the hexagons by scratch while sketching... not import another file

I mean, attach your model to this thread so we can look at it to determine where your problem lies.

the problem is that your second hexagon does not have a dimension constraining its size. So, it is free to satisfy the dimension you added in any way possible. The solve chooses to do this by increasing the size of the second one, not repositioning it. That is the difference between your case and the one in the video you shared.
