ModelCheck: Add check to define standard list for view scale in drawing

[jwagh]

Instead of some individuals using 'weird' scales in views or sheets within a drawing or accidental typos, like 9:33, it would be nice to add a check to define standard list for view scale in drawing.

While I agree that this is a needed check. it would be company specific as there is no drawing standard for views that I have been able to find. If there is an ASME standard for drawing view scales, I would love to see the reference. I did find an ISO standard  that listed view scales, I think. It was many years ago.

At a prior company, we had the following in our CAD guidelines document.

Drawing view scales shall be limited to the following sizes for metric drawings:

1:1, 1:2, 1:4, 1:5, 1:10, 1:20, 1:40, 2:1, 4:1, 5:1, 10:1, 20:1, 40:1

Drawing view scales shall be limited to the following sizes for English drawings:

1:1, 1:2, 1:4, 1:8, 1:16, 1:32, 1:48, 2:1, 4:1, 8:1, 16:1, 32:1, 48:1

It was very hard to enforce and seldom followed.

Ben, 

Yes, there would probably be a custom list in the modelcheck start file to specify what is allowed and not allowed. 

[DomenicLaritz]

Our drawing scales are based on the ISO 5455 standard.

[BenLoosli]

Can you list the scales specified in the standard?

[jwagh]

It should be treated like the parameter, layer, name lists... where it can be configured in the administrator 'start' files based on the business need of the organization.

[DomenicLaritz]

According to ISO 5455, the following recommended scales should preferably be used:

50 : 1	20 : 1	10 : 1
5 : 1	2 : 1
		1 : 1
1 : 2	1 : 5	1 : 10
1 : 20	1 : 50	1 : 100
1 : 200	1 : 500	1 : 1000
1 : 2000	1 : 5000	1 : 10000

It is also pointed out that if required for special applications, the recommended range of scales may be extended by multiplying by 10.

[jwagh]

Thanks for pointing out the iso standard. I believe the values should be customizable by the admin for those companies that don't follow iso standards or for those that want to allow just a subset. Also, thanks for all of those likes ;).

Drawings do not go away with MBD, and this sounds like something that has been missing from ModelCheck all along.  I do not see a working group for ModelCheck and will bring this to some other group if it fits into their scope.  I agree with all of the comments attached to this idea.
