unfortunately I cannot open the attached picture. But I think you get this error Message because the pads are createn a clearance violation. If you are using round pads, try to assign smaller ones. If you have rectangular pads, you possibly need to rotate them.
Thanks for your reply, henry.
let brief you more detail about my problem
I want to design a hexinverter- SMD
I have created 14 rectangle pads for this it.
Now I am in the process of placing the pads according to a certain order around the chip.in cell creation.
In the creation, I entered the distances into blank, following the datasheet of 74HCT04 in FARNELL,
But the system inform me I have DRV.
Thanks henry. now I know it is just a simple rotation problem.
I creat a horizontal pad in the padstack creation.
Thanks Vern, I think I will use your advise in the near future
Now I am just in the primary start.
