How to Draw Section B-B from Floor Plan & Elevation Plan

Creating a B-B section or longitudinal section is almost the same as the cross A-A section. Especially if you already have created section A-A. If you haven't created it yet, you may start from zero. Suggest, you should first read How to Draw Section A-A From Floor Plan & Elevation Plan beforehand.

  1. Check the completeness of pre-existing floor plans and section plans and then sync them

First, check the layout of all drawing whether they are in the right place as you wish. Then sync them by drawing a straight line from each elevation (view) plans. Horizontal lines use to synchronize between the floor plans and front view with A-A section. In other hand, vertical lines use to synchronize the floor plans with the front view and the floor plans with section pre-existing before. Swipe them if you must without overlapping others.

  1. Put the B-B tag in the floor plans

Section B-B is rather different from section A-A. Section B-B is built to make longitudinal section of building more reveal. Therefore, the placement of B-B tag is longitudinal in the floor plan.

Pin the B-B tag approximately in a position that can show all the details of the building. Create another longitudinal section when needed for more detail if demanded.

Make sure the section line is completely straight, not slanted, and unpin from the floor plan, so as not to cause confusion in drawing section B-B.

  1. Create a workspace for B-B section

Have them easy to draw and manage, all drawings must be sorted from right or left as you desired. Start from the front view, right view, rear view, left view, or vice versa. Then, you continue from section A-A, section B-B, section C-C, and so on.

The workspace area of section B-B is far from the right or left empty room of section A-A, which is not at upper area of floor plans.

Because section B-B is a longitudinal section, the current floor plan position cannot be projected onto section B-B. Therefore, you duplicate all floor plans and roof plans, you place it in a new place, then you rotate them according to the direction of the B-B tag. This position must not overlap all pre-existing drawing, or you just simply put it on the outer right or left side of the entire all the floor plans and roof plans. these duplicates be aligned in vertical and sequential stacking.

Draw the horizontal lines up and down the outermost edge, front view and section A-A if any. Also draw the left and right vertical lines of the outermost edge of the rotated duplicate floor plans. From the intersection of it becomes the work area of section B-B.

  1. Drawing Section B-B

Since no elevation views appears to be aligned with the B-B tag, such as the right-side view or left-side view, the front view appears unusable as a template. Therefore, you may draw it from zero.

Because section A-A already exists, it can also be used as a template for the internal area of section B-B of the building.

Duplicate section B-B, place it in workspace area and then, you synchronize it with the front view, and section A-A also, and the entire duplicate rotated floor plan. Finish it and that’s all.
