Entity to draw, select or modify Allows you to choose a different command/entity than the one of the selected entity:
e.i to draw a polyline after you « powerclicked » on a block.
Entity properties table :
At the left, active column shows the state of the variables in use in the drawing:
The column Source shows the characteristics of the selected entity:
It will be used as selection criteria for « modif » kind of action.
The column wanted conditions the next entity you will draw, or selection criteria for «select » kind of action, or the properties that will apply to selection set in « modif » kind of action.
You can change these characteristics either by directly entering new values in the editing boxes or for some of them, by pressing the right mouse button, which open another dialog box. You can therefore choose a layer, a color, a linetype, a name for a block or a file, a text or dimensioning style.
On the right, a "Toggles" Y/N column type lets you check (or uncheck) these modifications.
For instance, if the current layer is « 0 », and you type « road » in the corresponding editing box, (assuming this line is not checked) Powerclick will not pay attention to the « road » argument and the new entity will be created in the layer « 0 ».
Action :
If you choose Draw, PowerClic changes the parameters creation entities and will suggest the execution of the associated command. No entry will usually cancel this command.

If you choose Cancel, PowerClic will not change anything and go back to the AUTOCAD prompt.
WARNING: The icon from PowerCxref will open the same dialog box, but the options «modify» and «select» will not apply to the objects contained in the external reference of the block.
