Hi
For all of you that have this problem. There is a simpler way to do this.
When the files are converted from the original ones to Altium there are no errors, but nothing appear on the PCB Window.
The reason is the difference viewing areas on the two softwares.
After you importing the Layout from Orcad. You must go to Altium Designer PCB list tab there you will find that almost all references (x,y) are bigger than 3000 mm.
Now you have make fit board, then select all objects outside area and define a small area on the bottom left corner of the pcb Window.
This is almost done, now select the command MOVE Selection by x,y.
enter -1500mm in x and y.
Now all the components are on the viewing area.
attached files with converted files.
Regards
