To insert a symbol by dragging it from the Resource Browser:
Click the symbol in the Resource Browser and drag it to the desired location in the drawing. To insert the symbol into a wall, the symbol must have the Insert in Walls option enabled (see Creating New Symbols).
The symbol cannot be rotated during insertion, since the Symbol Insertion tool is not automatically activated. When a symbol is dropped onto a wall, round wall, or roof, Vectorworks inserts the symbol into the object using the default flip value and insertion point.
A symbol inserted by dragging and dropping is placed on the active layer plane by default. Press the Option key (Mac) or the Alt key (Windows) while dragging and dropping to place the symbol on the working plane.
The symbol is inserted.
If necessary, edit the symbol rotation or flip from the Object Info palette.
