You may find that you need more control over the positioning in order to move connector J2 into
position. Remember that objects are linked to a snap grid so all we need do is reduce the snap
grid via the options on the View Menu, for example to 1mm snap.
If you are working in imperial units you can either change the snap to 25th or use the ‘M’
shortcut to switch to metric units
Now that we have the granularity we need, simply right click on the part to select it and then
drag it into the desired position. We can move the connector closer to the board edge if we
move the part label underneath the part. Again, the process is identical to the one we covered in
the Proteus tutorial – remember this time to right click on the label itself and not the component
body.
As you place components and ratsnest lines appear the connectivity status also will update to
show the number of missing connections.
