Revit 2017 API - ElementTransformUtils.RotateElement is very slow

mahmouds12 — Sun, 29 Jan 2017 16:05:18 GMT

Hello all,

I am creating a Revit 2017 plugin in which I use "ElementTransformUtils.RotateElement()" to rotate a lot of Revit Elements
The problem is that this method sometimes takes more than 1000ms for each element on a high performance pc... and when creating 100s of elements, this will make the overall process very slow

First Question: Why does this method takes a lot of time?
Second Question: Is there an alternative or a work around to rotate any element without using "ElementTransformUtils.RotateElement()"?

Thanks

hard too say with this less information. I recall having a kind of simular case, where the preformance was speeded up by not doing a transaction for each rotation, but group things within one transaction. But I know sometimes the code doesn't allow that.
