Green Tick Greyed Out in Slab Tool

[Constance C 0]

Hi all, 

 

I'm new to Vectorworks - transited from Revit and AutoCad. 

Sorry if this question has been raised before

 

I tried to create slab from polyline, but the green tick button greyed out. 

The green tick will resume to normal if I pick "Picked Wall Mode"

Anyone can shed some lights on what's happening?

 

Thank you!

Hi @Constance C the green tick is solely there for use in Picked Walls Mode, to tell VW to go ahead + create the slab based on the walls you selected. With the other modes there's no 'go ahead' prompt needed, so Polyline mode for example you just draw the shape you want + click on the start point to complete the object + it'll be a slab. Check what it says at the top of the Object Info Palette: it should say 'Slab'
