How can I select all the walls in Dynamo like I can select using the Tab key in Revit?
Hi @AmolShah, you have several options here.
Do you mean all the walls in the entire project?
Do you mean all the walls in the active view?
i think it is not possible by selecting model elements node, but in another way you can select your models from revit before running the script, then use CurrentSelection node from spring package to get what you selected before
As @khuzaimah.ElecEng said, one of your best options is to pre-select your walls in Revit. You can also use a custom selection node (like Data-Shapes) that allows you to tab-select in Revit.
