hii all,
How to make different thickness in same PCB(eg: 1.6mm and 1mm)? and 1mm thickness should be in round shape.I am using altium designer 14.1.
thanks.
 

The question isn't very clear. What means particularly "1mm thickness should be in round shape"? Can you sketch the intended geometry?

Generally, you can have parts of the PCB milled down to smaller height. Details should be discussed with your PCB manufacturer.
 

I hope the 1mm thickness PCB should be round shape & 1.6mm PCB in another shape. These 2 PCBs are combined together.
It is possible by using rigid-flux PCB design or at the least the PCB should be multilayer. How many layers in your design.

Regards
Udhay
 

Define your board in "Layer Stack region" option 1 using define split lines. Once you have your layer stack regions created you can then go to normal pcb ( 2 ). In design/layer stack manager you will then have these different stack regions appeared. You can add/remove layers/prepregs as you like to suite your build/thickness.
once all done you can place this layer stack into drawing.
hope this helps
thanks
