protected memebers of parameter class

[OR_AND_NO]

Dear Sir,

Could You please tell me does exist the safe way to change for example IsReadOnly property of START_EXTENSION (parameter.Id = -1152357) builtin parameter of an beam element using RevitAPI and IL code.

Dear Or and no,

No, I am not aware of any such possibility.

There is a reason why it is read-only.

Presumably it is rendering a specific aspect of the 'view' of the parametric BIM model and driven by other factors.

Therefore it cannot be changed.

Attempting to change it would be in conflict with the other paramerters that really are driving the model.

I hope this clarifies.

Best regards,

Jeremy

Thanks!

When i did try revit 2015 i found that IsReadOnly property in START_EXTENSION parameter of a beam shows existing or not a constructional link between this beam start and another beam body.

It is possible to change IsReadOnly property on view by mouse, therefore i assume that it is a safe operation in UI mode, also i assume that possibility to make same operation in API mode is safe too.
