How does revit assign lineweights to custom view scale / scale value drawings? Revit 2020

Anonymous — Thu, 11 Mar 2021 10:51:33 GMT

Hi there,

Trying to set up a good revit template for the office, part of this is setting up line weights so we get a sexy drawings, quicker...

As you may know, line weights (manage>additional settings>lineweights) are assigned against standard view scales and there is a pre-determined list of scales you can add to the line weight matrix. I have two things to clarify:

- Is it possible to add a custom view scale to the list provided (image below), we need to use 1:1250 for every UK project, and it isn't on the list.

- I need a general explanation of how Revit assigns lineweights to custom view scale / scale value drawings, so for example if i set a drawing at 1:400, is it trying to scale proportionally between given lineweights for 1:200 and of 1:500?

Unfortunately, till now it is not possible to add a custom scale to line weight list.
From a personal practice i used a simple formula to determine which line weight is assigned to a custom scale as following:

I add 2 scales and divided them by 2 and any number above the mean will follow the larger scale.

So if I create a custom scale 1:400 (1:400 is between 1:200 and 1:500)

(200+500)/2=350 which is <400

So the 1:400 will follow 1:500 line weight and any custom scale <= 1:350 will follow 1:200

Hi there,

I don't see an answer to the 1:1250 custom scale question. UK users must use 1:1250 and 1:2500 scales all the time. These are industry accepted planning scales for local authorities. We have less use for 1:1000 and 1:2000.

Is it possible to create a permanent custom scale in a template so that it is available in the drop down list for every view. Or another way to permanently save the scales? This would really save us some time.

Ta!

You can use the View Template to change the custom scale you want and any drawings you wish to apply that custom scale to; use the view template you create. I hope this answers your question.

The Question is not answered, if 1:2500 or 1:1250 is required then the Line Weights settings for the desired Scale for the View should be simply applied.

Apparently, the requirement is not so widespread as some are trying to make it seem or Revit handles it in a logical way. If it were such an issue, I would like to think that Autodesk would have addressed it already.

Until those scales are implemented into the standard scales list. I suggest that you use a view template to set these lineweights if you desire something other than what Revit does automatically. Save it in a separate file and transfer it when setting up new projects.

Also, visit the Ideas forum and vote up any posts requesting this. If it is so dire, you should not have a problem finding many posts suggesting it be implemented immediately.

Good luck.

When using a custom scale the lineweights will take on the defined weights for the closest defined scale.

For a drawing at 1:1250 if you add the 1:1000 scale to your lineweights it will use those weights as that is the closest scale to the custom one.

For a drawing at 1:2500 if you add the 1:2000 scale to your lineweights it will use those weights as that is the closest scale to that custom one.
