Floor plan section cut line.

Plan drawings are in fact a type of section but they cut through the building on a horizontal rather than vertical plane. Click the break line edit button and then click in the middle of one of the clip planes to place a break. In your floor plan view you can step your cutting planes by selecting the camera s symbol to highlight it. Interior and exterior elevations are noted on the floor plan in much the same way as building section cuts figure 6 29.

Off the floor was a guideline that had to be fudged all the time in order to produce the clearest possible floor plan. Figure 6 28 shows how building section cuts are indicated on floor plans.

Therefor you see in the cut anything that the plane passes through. This means that you have an imaginary plane cutting through the building at an elevation of 4 feet above the floor. The direction of the plane through which the section is cut is often represented on plan drawings and elevations by a line of long and short dashes called a section plane. It is also called a plan which is a measured plane typically projected at the floor height of 4 ft 1 2 m as opposed to an elevation which is a measured plane projected from the side of a building along its height or a section or cross section where a building is cut along an axis to reveal the interior structure.

If the section line is invisible change the floor plan scale factor back to a value that enable you to see the section line. It displays a list of section views and floor plan views.
