Assembly View plane not perpendicular

[Francis.Foley]

Has anyone come across this before look at the attached assembly drawing, it is not perpendicular on the screen, it is out by a few degrees. Anyone know who to fix this?

Look at the gap on top versus the gap on the bottom.

I am using Inventor Pro 2014

this appears to be an assy file.

What you will need to do is go back thru the history of how this assy file was created and inspect each part file.  I suspect one of your part files is out of whack - hard to tell though without the actual files themselves.

My eyes are not that good any more - I cannot tell if something is perpendicular to any plane using just a picture.

I thought the first item in an assembly was grounded.

[ampster401]

recent versions of Inventor have that option disabled, so you would have had to manually enable it.

Still, you'll have to go thru the assy starting with the 1st part you inserted or placed into it.

If you'd like some assistance and the files are not propietary in nature, try zipping them up and attaching them to this thread.

I just started again, there was only a few parts in the assembly and this time I made sure to ground the main part. Thanks for the tip, I must look as the assembly application options and see if i can ground the first part by default.

Yes, you can set it back to the behavior of previous versions in Application Options,

or

when placing the first component, right click and select Grounded when placing it.

Hi! It looks like the component which the view is based on is sllightly off origin planes. You can right-click on the component in the assembly browser -> iProperties -> Occurrences. Look at the offsets to origin planes. They should all be zero. If not, clear them to zero and hit Apply. Then ground the component after that.

Thanks!
