Setting a drawing scale to a view

[Anonymous]

Hi,

I am trying to create a view in the revitapi (c#, 2019) and cannot set the drawing scale to it.

Any suggestions?

View has "Scale" property. Usually it is enough to set a value. The only problem could be if this value is controlled by view template.

ViewPlan viewPlan = ViewPlan.Create(currentDoc, viewFamilyType.Id, levelId);

Is the code I've used to create the view, how do I see the view template?

[aignatovich]

There are several options:

1) check viewFamilyType.DefaultTemplateId property

2) check viewPlan.ViewTemplateId property after a view plan was created

viewPlan.ViewTemplateId  - null

viewFamilyType.DefaultTemplateId - gives me an ID

How do I change the drawing scale knowing this? 

Edit:

When i do try and set it, it says the parameter is read only.

if viewPlan.ViewTemplateId == ElementId.InvalidElementId just set viewPlan.Scale = 100 (for example)

In other cases, get view from ViewTemplateId:

var templateView = (View)doc.GetElement(viewPlan.ViewTemplateId);

then check this expression:

templateView.GetNonControlledTemplateParameterIds().Contains(ElementId(BuiltInParameter.VIEW_SCALE))

if is is true then you can set viewPlan.Scale = 100 otherwise you can't set it, because it is controlled by template
