vertical constraint moving something else

Christopher2222 — Wed, 30 Jun 2021 00:50:07 GMT

What am I doing wrong here? I am following the woodworking part 1 video https://www.youtube.com/watch?v=HXiKNqBhlqQ and at 3:25 to 3:40 when he moves the center piece over. ( I am using Inventor 2015) When I use the vertical constraint it doesn't move the center piece over, it moves the line to the right over to the left into center.

Maybe he does something I'm not seeing. How do I get my piece to the center? What could be going wrong?

Have you dimensioned the divider width before you are using the vertical constraint? Seems like you left a step out.

Can you post your part and I'll have a look?

Hi! I guess your sketch coordinate is probably 90 deg off the one from the video. So Horizontal becomes Vertical or vice versa. You can check it by Finish Sketch -> right-click on the sketch -> Edit Sketch Coordinate.

You can simply use Horizontal constraint instead. Please feel free to share the file here. It should be doable. Forum experts can help take a look.

Many thanks!

Thanks guys.

Ok had another go at it from the beginning to see where I went wrong. Somehow the thickness dimensions on my side pieces disappeared ... oh wait! ok now that I think about it, when I trimmed the side pieces those dimensions disappeared (I'll have another look) because I know I initially dimensioned them.

**edit added info** Yes that's exactly what happened, trimming the side pieces got rid of the side thickness dimensions - and he doesn't show it in the video re-adding the dimensions, it was very subtle that those dimensions just appeared although he mentions "making sure all the necessary dimensions are there" the actions to show what happened weren't done. So being a beginner I was puzzled by what happened. No worries now.

Anyways thanks it was a missing dimensioned part.

Also what else isn't shown is that the trimmed lines had a collinear constraint applied otherwise two dimensions would be needed.
