Roof slope default

[patricks]

When you create a roof by footprint and add slope-defining lines, the slope defaults to 30 degrees. If your slope units are set to rise / 12", then that results in a slope of 6 119/128" : 12. Is this something hard-coded or can it be changed somewhere?

LOL, ive often wondered that myself. The 119/128 always cracks me up...

[patricks]

Yeah, the tangent of 30 degrees, multiplied by 12 gives you 6 119/128.

Fix it in your template, and then the slope will be whatever you set from that point forward on all new projects. It was originally done in metric and slope was set by degrees. Converting to imperial and x/12 slope gave the funny number.

what am i missing...trying to change the default defining slope in our template from 30 to say 22.5 and it doesn't want to save. It keeps reverting to 30 again and again. This is in 2011.

When you change this option are you changing when your about to draw the line or after you have drawn the line? You need to do it before you draw the line. Then it will keep that state everytime. Once it has been changed then you can save your template file like that.

I can't change the slope before drawing or picking walls, and when I sketch a line the 6.928 remains the default even after changing adjacent sketch lines. What am I doing wrong? I've wasted way too much time on this seemingly simple change -- please help!

You haven't wasted any time at all. You are learning to pilot a 747.

The trick is to sketch all of your lines first, then with no lines selected, change the slope in the properties. Tip: if something is taking a lot of time in Revit, it either cannot be done, or you are doing it wrong, move on to the next thing and come back to it later. Once you get used to the workflow, you will find there probably was no need for what you were wasting time on, like a 'default' roof slope.
