Question about symbol libraries in 28pins project
goldchan , 07-22-2021, 02:28 PM
I am following the lecture materials.
I understand I am using a different version (21.5.1.) of Altium design from one of the used Altium.
Mostly, I could follow the lecture materials with a new version of Altium.
However, one major difficulty to duplicate the lecture material is that I wasn't able to match the scale of a component for the symbol libraries.
As an example of the attached image, for 1M Register, that I wasn't able to figure out why they look different.
In the lecture, a pin length is set to 10 (old version doesn't show the unit, but I guess it is 10 mil) and I guess the visible grid is 20mil and the snap grid is 10mil as shown in the below picture.
In my environment, I also set the visible grid as 20mil and the snap grid as 10mil.
and I set pin length 10mil, but the relative size of the designator and name of a pin are quite different even If their size is to be the minimum (6).
I wondered what I am missing here. I wasn't able to figure it out. This is not only for the Resistor but also all other symbols, especially AND logic symbol.
Could you point what I missed?
Thank you

The old Altium's schematic library units are in 10's of mils, this means if the old Altium shows 10 it is 100mils in the new Altium. Hope this helps.
