let's set up blender 3.0 for 3d printing and precision modeling if it's the first time you're
running blender you'll have this introductory splash screen i would suggest that you change
your space bar to search but i'll show you how to do that in just a moment i'll hit next and then
i'll click on the background we can see that everything looks really small and fine and it
looks like we're in meters as well so let's sort all of this out let's go to edit then preferences
and the first thing i want to do is right here where it says resolution scale i'm going to change
that to 1.25 because i'm working on a 4k screen it'll make everything a lot more visible now i
also like to change my line width over to thick as it just makes everything even more visible still
then i'll go to system and i'll crank my undo steps to the maximum amount now if you missed
that splash screen let's go to key map and here where it says spacebar action by default it'll be
on play i would suggest go for search because we don't do a lot of playing when we're doing
precision modeling then let's click on the burger stack hit save preferences because i have had
times that it doesn't auto-save clicking out of there we're going to go to our scene properties
right here we're going to go to our units i'm going to change our length from meters to
millimeters now be careful when we press n to open up our side menu we've changed the representation
of the units to millimeters not the actual global scale of it to do that we need to go to unit scale
and set that to 0.001 and now the unit scale has changed to millimeters but our overlays have gone
so let's go to our overlays they have their own scale option right here we're going to change that
to 0.001 so that they reflect our unit scale then i'm going to turn on my statistics because i like
to have a little bit extra information and down here on my bottom bar i'm also going to turn on my
statistics i'm going to turn on my video memory my system memory and my statistics right there
okay now if we zoom out you can see that things are going to start clipping out really quickly
that is due to our clipping plane let's go to our view and these numbers right here that's
our clipping plane i set this to 0.1 and i like to put in two zeros for my end and now you can
see we can see a lot more of what's inside of our plane now let's set up our scene how we want it to
be every single time we start a new general file so i like to have this over in item i also like
to have this over in my active tool but there's one other thing inside of edit mode this is set
up like this my lines are really small and fine my vertices are just a little bit too small and
my lines are black i like to have them a different color so i'm going to go to edit preferences then
i'm going to go to my themes right here i'll find my 3d viewport and i'm going to change my
wire edit this one here i'll click on this little arrow bring this up to a nice bright blue like
so then i'll scroll all the way down to where i get my vertex size and like to change this to
a minimum of four i will save my preferences once again and click out of there and you'll
see how much more contrast there is with that especially when you're working with individual
vertices in such a manner like that okay going out of edit mode with tab let's select everything
because i don't want to start up with all of this every single time i also like to have that in tool
and i also like to have that closed down so the crucial part here is to go to file then defaults
save startup file and confirm that saving if you do not do that every single time that you go
file new and create a new general it will put everything back to how it was your units
would still be in meters and it wouldn't be in millimeters so make sure you save everything
you've done once you've set it up how you like it now that you're all set up with blender you might
be looking to learn more well i have an entire free precision driven course here on youtube it's
over 10 hours long very technically deep but you only make one a tiny little model in it however if
you're looking to learn blender through actually making 3d printing projects head on over to maker
tales academy where you learn everything you need to know in blender for 3d printing all the links
for everything i've just mentioned are going to be down in the description and a huge thank you
to my patrons you guys are absolutely awesome and without your support i wouldn't be able to
make maker tales and if you're enjoying what i'm making here you think i'm worthy of your support
i would love to see you there too and don't forget that we have a discord and that's linked
down in the description as well thank you for watching keep making and let the quest continue
