ADS help" How to draw via between different layers

Hi, I have a simple question about drawing vias between different layers in Agilent ADS layout windows. Thanks.

its very simple, select any layer which is free draw the shape of via, like rectangle to make box kind of via, circle to make cylinder kind of via, stright line to make planar via, (it is automatically extruded in to 3D by software), now go to subsrate create/modify, click layout layers tab, click the substrate layer in via you want to punch via, then on right you will find the drop down menu select the layer on which you made the shape of via, and click the button "via" which appear above apply button, thats it

Hi, mfarhan1. Thanks for your help. Actually I just saw your answer in the other guys post.

Well, can I ask you one more question, can ADS layout shows the 3D visualizations of the circuit? If yes, how? Thanks in advance~

yes that possible but its only after simulation, click mommentum -> post processing -> visualitzation, there you go
