Question about modelling birdcage I have been trying to model a fancy birdcage, similar to the one seen below, but I have run into a problem: I have created the bottom and the bars, the problem is I want to place the bars in a perfect circle and placing them by hand is tedious and often leads to inaccuracy. Is there any way I could, for example, place the bars along a circle curve? Or is there any other way that I could place the bars in a perfect circle? 

I have not included a .blend file or a screenshot of my setup, because it is a very simple setup, just imagine the bottom as a default cylinder and the bars as the default bezier curve. 

Thank you in advance!
As mooboots said in his comment, use the array modifier:


Create the curve of the bars and and empty
Make sure that both the empty and the origin of the curve sre in the center of the disk
Apply all eventual rotation and scale of the curve and the empty
Create an Array Modifier on the curve
In the modifier, disable Relative Offset and enable Object Offset. In the field below insert the empty. There shouldn't be any visible changes
Rotate the empty on the Z axis using a nice angle (like 5, 10 or 30 degrees) ans increase the Count slider in the modifier
Done


You can still change the curve or the angle, just remember that if you want to move them you need to always move the empty and the curve together
