The two planes are not at different heights. Their locations relative to the walls beneath them are different. A wall closer to the high edge will need to be higher to reach the roof plane. A wall closer to the low edge will be lower. Link to comment Share on other sites More sharing options...
Alaskan_Son Posted December 20, 2018 Share Posted December 20, 2018 I think the baseline concept gets misunderstood by even some of the most advanced users. In a nutshell, the baseline is nothing more than the main pivot point and control for the roof plane. Consider a perfectly round roof plane. What are you going to use to determine where it pivots, or the line that is used to determine the roofing material orientation? That's the purpose of the baseline. The baseline can be at any angle in plan view, at any angle with regard to the roof plane it produces, and can be adjusted to an off angle in 3D even, but it provides for the single constant pivot point required in order to maintain any sort of logical control over how the roof is generated. The baseline is TYPICALLY located over the exterior of the wall's main layer but it certainly isn't always located there. If for example you have 2 different roof pitches and you want the overhang to remain constant, Chief will automatically move the baseline to accommodate during an auto-build. Yes, you could also adjust the baseline height instead, but Chief will automatically move the baseline in order to maintain a constant baseline height...this behaviour helps make the Make Roof Baseline Polylines tool possible. 1 3 Link to comment Share on other sites More sharing options...

This was very well explained! I tried to use the liked thing in the lower right hand corner of the post but I cant figure out how that works so I'm just telling you.

tommy1 Posted December 20, 2018 Share Posted December 20, 2018 Rocky, does all of this explain things to you? More importantly, do you agree that you should start your roof planes on the outside of framing? Link to comment Share on other sites More sharing options...

M. What the difference between "Like" and "Approve" (upvote, downvote)? In other words you have three categories; Like, Upvote and Downvote. I just don't get how they are supposed to work together or which one to click on. Link to comment Share on other sites More sharing options...

CJSpud Posted December 21, 2018 Share Posted December 21, 2018 Rocky: Here's an exercise for you to try. Open a new plan with no walls, nothing in it. Now draw a roof plan in the plan. Ask yourself, why did it show up when there are no walls yet? Select the roof and open its dialog (specifications) box. Why are the settings what they are? Now, draw a cross section through the roof. Can you tell where the roof is located with respect to Chief's "0" elevation (usually the top of the subfloor ... structures with framed floors ... or top of slab for structures with slab floors. Go back to your plan view and off to the side of your roof plane draw walls for a small structure. Go back to your cross section now and see the relationship of the roof plane to the 4-sided structure's walls. Draw a CAD line horizontally from the top of one of the walls through the roof plane. Look at where the CAD line crosses the bottom edge of your roof plane. Now draw a temporary dimension or a point to point dimension from the CAD line's intersection with the bottom of the roof planes framing member to the top of that framing member. What is that measurement and what does it mean? Can you find that number anywhere in the roof specifications. Hopefully you'll start to understand some of trig/geometry/nuts and bolts of what goes on within Chief when you build a roof .... which all sort of magically happens based on "YOUR PLANS DEFAULTS". Everything you do in Chief when building walls, roofs, and other parts of a building's structure are based on the plans defaults. When you start changing defaults or "moving things around", the model reflects those changes. Chief will do the best it can to change the model based on what you do but that doesn't mean the model will be correct after you've made some changes. If you start getting warnings or error messages after doing something, Chief may be trying to tell you there's a problem doing that and you might have to "undo" and try a different approach to what you are doing. That's all a part of the learning process with CA. All Chief users eventually learn how to use the program efficiently. I was a little slow grasping roofs myself, especially manually building roofs. I ended up driving up to Coeur d' Alene and taking an hours training with Mont Stevenson (CA trainer) years ago and that session really helped me get over the hump with being able to build roofs as they should be. Even now, years later, I will run into a roof design that tests my abilities. Please take the time to study how to use Chief. Read the manual; read help database articles; watch videos; read the threads on Chief Talk; do whatever it takes to expand your understanding of this very powerful program. And most of all ... PRACTICE as you learn...!!! I hope Tommy and you have a good session. He's been using Chief a long time and really knows his stuff. Good luck.

M. I will downvote a post if I think it is counter productive. One of my pet peeves is when I see a response that demonstrates that the person didn't read and understand the OP. I usually downvote these, especially if the post expresses frustration towards the OP. 1 Link to comment Share on other sites More sharing options...
