Picked a 0.5mm mechanical pencil over a 0.7mm for drafting

I switched to a 0.5mm lead for my detail drawings last month. Tried it on a commercial floor plan in downtown Austin. The thinner lines looked cleaner but kept snapping on the vellum. Switched back to 0.7mm for the heavy stuff. Anyone else deal with lead breakage issues?

Try rotating the pencil as you draw, that helped me stop those tiny snaps.

@susan81 here. The lead breakage thing is like that perfect pair of jeans that rips the second you sit down wrong. It's the same frustration as when your phone charger stops working just out of arm's reach. @hannah_wells suggestion about rotating the pencil is actually smart though. I've noticed that in life, the small things we do over and over need tiny adjustments to stay working right. Like how I have to tilt my coffee cup a certain way to avoid spilling on my keyboard. It's all about finding that sweet spot between precision and practicality.

Rotating the pencil sounds simple enough, but does it actually make a difference on vellum compared to regular printer paper? I found 0.5mm holds up fine on bond but gets fragile on the slick drafting film where you have to press harder. Had a set of blueprints where I snapped three leads just outlining a single window frame. Maybe it's the angle I hold the pencil too, like tilted more than 45 degrees when I'm doing tight corners. What kind of pressure are you using with the 0.5mm, just light feather strokes or something with more weight behind it?
