I am having the issue of connecting my voltage regulator to the trace. The trace must be thick but the pins are too small.
What is the best solution? I am using proteus. Does making a solder Paste shape work?
Thank you!

A trace's resistance increases with length, and decreases with thickness. So the thickness is the more important the longer the trace is.
For a very short segment of the trace, the thickness does not change the total resistance by a noticeable amount. (Connections to through-hole pads are often deliberately made thinner to increase the thermal resistance; see Does adding thermal relief on PCB increase electrical resistance?)
So the shape of the connection does not really matter. The best solution is to not worry about it.

So i shouldn't worry about maybe this segment heats up and causes issues – Anthony J Feghaly Apr 27 '22 at 15:05

Assuming a current of 1 A, you would need a trace width of less than 5 mil for a temperature increase of 50 °C. – CL. Apr 27 '22 at 18:32

okay,thank you CL! – Anthony J Feghaly Apr 28 '22 at 08:28
