    I haven't had the opportunity to do curving lines at material transitions or in general, only circles until now. I have an upcoming job that requires a few curving transitions with same height material and I'm wondering if anybody has any methods that they can share.
    Here's a picture for reference

    Use 1/2" pvc or flat metal on edge. Pvc will bend.

    The conduct type electricians use are good as you can join them together then use an Armstrong type recesser to mark the second type of flooring on the join
    Unlike some layer I saw here trying to line up the tubes again to join the two different flooring types

    Drink a 12 pack before you go. There won't be a straight line on the job.

    Jokes aside, you have to be creative. think outside the box. I have used 1/2" PVC & some blocks of 2x4 with great results. Hot melt the blocks strategically to hold your radius & make your mark.

    What materials will be transitioned?

    Anytime i have "designer" lines... better know as the reason i hate designers, i make them give me the radius. Then i go down to my local fabricator and have templates made. Templates are cheap, time is expensive.

    Wolff makes a circle / radius cutter/scriber. It'll do just over an 8' diameter circle / curve. Our guys around here do what Mark does and make metal templates for the wavy odd stuff like your picture.

    We also send the drawings over to a shop who makes us metal templates.

    you guys are upper crust... I get them made frim coraplast or whatever it's called. Dirt cheap... get two radius per piece one on the outer and one the inner.

    Did a 54' radius one day free hand... let's just say there is a reason I get templates made

    It's fairly easy if you have specified radius measurements and fixed/hard dimensions on the blue prints. I've used felt paper to arc out the radius and then tranfer that line to the floor for glue and then overlay the paper for cutting the material. GENERALY though the sort of wobbly design I see in that photo is not a's oblong/oval and reacts to whatever the walls or corridor lines are doing.

    We also use PVC conduit for simpler stuff. When there's no hard dimensions on the plan we lay out the pipe roughly, draw lines on the floor and get the Big Shots to sign off on the layout before we cut anything.

    I saw a guy with some fancy schmantzy flexible rods about a year or so ago on a huge Medintech job with tons of circular/oval/radius designs. When he set the rods down where wanted he layed 2" blue tape along that line. Then they'd glue to the tape, overlay the good, tape over the tape and cut along that new tape line. It took forever and a day but was slicker than shit-----CLEAN. I meant to ask him where he got those contraptions but I was only there a few days near the end and he's gotten a job with the City.

    My installers have done the felt paper method for those instances with sheet vinyl as well - most of the stuff the designers are drawing around here these days is weird curves cut into plank LVT, argh! That is really where we have used the metal's pretty much a necessity.

    making templates is all well and good for small radius curves, under 15 feet or so, I find it hard to be consistent with anything larger. Steel string and a scribe needle only get you so far.

    I use insert metal. (From a snap track transition) On edge. I rivet 2 or 3 lengths together. The longer it is the more flexible smooth the curve will be. If you look at the 7th photo you can see the metal transistion riveted together to make the curves (Near the broom)
