Drawing dimensions off in every view.

[raidercad]

In all my drawings, all dimensions in every view are off by a small amount. I have created numerous parts and drawings and they are all off. I have attached a simple part and drawing. Any insight would be appreciated.

Hi,

This happens when you display too many digits.

Thanks for the reply gunther,

I have a hard time believing that is the case. Too many decimals. Why would there be an option to look at that many decimal places if they are not going to be correct? This doesn't occur in SolidWorks, Inventor, or AutoCAD.

I realize that I used the maximum number of decimal places in my example and that is not how a drawing would be dimensioned for manufacturing purposes. There are times when you need 4 decimal places and this is where I ran in to the issue of the dimensions not being correct. If this is the case then this is just another quirk that makes using F360 seem like it is more trouble than it is worth.

I think the problem is because you've used the ASME template. I've seen a few odd problems if you use mm and the ASME template because it's imperial, in this case you are seeing a conversion error.

If you use the ISO template the errors go away.

@Phil.E  I've brought this problem up before where there are errors caused by the default imperial template. Is anything being done to help with this? Really Fusion should have 2 templates for ISO and ASME (4 total) 1 metric and 1 imperial for each so these conversion errors don't come up.

Thanks Mark

@HughesTooling Thanks for letting me know. As with all the issues related to ASME/ISO templates and in/mm units, I've reported this to the drawing team with links to this post and the data provided.

And you are correct: every issue we've discussed is related to using ASME templates with mm units. The drawings development team is aware of this.

Mark,

Thank you for your response. This makes more sense. I currently teach high school Inventor in CAD/Engineering courses and we are looking to transition to Fusion 360. It is definitely proving to be more of an issue than I had anticipated, but I will keep plugging away.

Hi,

This shouldn't be a problem for education. Using greater than 4 place precision in dimensions is not typical in manufacturing. 

Is there a subject area you teach that uses five place precision? 

[raidercad]

No, there is no reason for five decimal places.
I just happened to accidently set a template to four decimal places and I
ran into a dimension that was minutely off. I went back and looked at all
my drawings and ran the decimal places out on all dimensions just to see
what was going on and saw they were all slightly off. I had
initially thought that maybe there was an issue with the UCS and my
drawings were not projecting properly. I just did not understand why the
numbers were off at all.
Now that I know what the problem is, I am not too concerned about the issue.

Hi,

Just following up. The fix for this was released in the April updates. 

@raidercad  and @HughesTooling  Can you please confirm this meets your expectations now?

Thanks,
