better math in dimensions, please.

[i-make-robots]

The app will accept "3/8 * 1in" as a dimension.

The app will not accept "3/8in".

The app will behave the same for other units of measure.  mm, cm, ", ', and ft tested.

I have voted for this as it needs improving but thought I'd pass on another workaround, it will except "3 in /8"

holy moly - "3 in /8" is the most stupids way to accept something.

for a pro app not working with dimensions in a logical way is a hard face palm 😉

[HughesTooling]

Yes seems crazy. I don't know where these rules on the use of units in equations come from but it's not unique to Fusion. I just tried out the same example with another solid modeler that use the similar rules and got the same problem!

Looks to me the typical "CAD was made for engineers and bad practice".

I often find many of those old decissions still being present in todays modern software.

Hey seems to be an industry standard 😉

The title shoud be "more conventient math" and yes that would be nice.

However, mathematically the nomenclature used by Fusion 360 is perfectly correct!

What I hear you saying is

It might be correct but is the flow more logical?

just speak this out loud:

3"/8 vs 3/8"

3"/8 written differently is like: (3 inches) / 8

commonly people say 3/8 of an inch and not 3 inches devided by 8

In other apps I can just write: 1/2m-5cm

and it creates a 45cm unite

[i-make-robots]

I don't see how mixing measurements should matter.  The parsing system could handle arbitrary (but syntatically correct) unit changes.

The problem is that 3/8in is ambiguous. Do you mean "3 / (8in)" (ie 0.375in^-1) or "(3/8)in"? It might be "obvious" to you that you of course don't mean an inverse inch, but it's not an obvious interpretation of that expression.

Does it accept "(3/8)in"?

Hi all,

Thank you for pointing out this issue. This is definitely something we are investigating. I am placing this under future consideration because it will take quite a bit of time to complete this task. We need to make sure we migrate all of your old dimensions and equations without creating issues. 

Thanks,
