    How Do You Calculate the Base of a Triangle for Scribing an Arc in Construction?

    Yes i know what you mean but that solution does not enable me to physically scrib a line on the end of string to the pickets. And will involve about 800 separate calculations for all the spans. The largest single point radius i can scribe is 2300mm which means that some of the pickets won't...

    How Do You Calculate the Base of a Triangle for Scribing an Arc in Construction?

    Thats the way i first tried and is in the beginning of this post It gave me a 5238mm radius whichn is not possible to measure because house is only 3000mm of the ground. Which means i can not scribe the line because the maximum radius i can scribe is 3000mm -700mm length of middle...

    How Do You Calculate the Base of a Triangle for Scribing an Arc in Construction?

    The 3280mm cord was for a circle the 3132mm cord is for an elipse the 450mm rise is fixed regardless of curve or span No it is not possable to use a template would be to difficult I only went for the triangular method to give me a means of laying out the curve in place over different spans...

    How Do You Calculate the Base of a Triangle for Scribing an Arc in Construction?

    Hi Studiot OK the shappe of the curve is not important but it must be repeatable on different cords So if i run the cord from the center of first picket to the center of the last picket the cord length will be 3132mm and from center of cord to top of ellipse will be 450mm So i need a...

    How Do You Calculate the Base of a Triangle for Scribing an Arc in Construction?

    HI i have a problem working out the correct arch under a queenslander house 3 metres in the air The span etween the pillers is 3280mm So the cord is 3280mm and from the center of the cord to the radius is 450mm I have worked the radius out to be 5238mm Since the house is only 3000mm of...
