What Is A Cross Section Drawing

Cross sections make it easy to draw details of solid objects.

What is a cross section drawing. Choose a cross section line. In technical drawing a cross section being a projection of an object onto a plane that intersects it is a common tool used to depict the internal arrangement of a 3 dimensional object in two dimensions. This would enable the viewer to see all the various components that make up the entire element being drawn.

With computed axial tomography computers can construct cross sections. A view into the inside of something made by cutting through it. The easiest explanation of a cross section is to imagine that the construction component has been cut across its center.

A cross section imagines what something would look like if you cut it in half or more or less in half and looked at the surface that was exposed by the cut. For buildings this can be useful as it gives a view through the spaces and surrounding structures typically across a vertical plane that can reveal the relationships between the different parts of the buildings that might not be apparent on plan drawings. The cross section as shown on a drawing is a depiction of the construction component from the side of the component.

In geometry it is the shape made when a solid is cut through parallel to the base. It is traditionally crosshatched with the style of crosshatching often indicating the types of materials being used. On the floor plan drawing above at the upper and lower left there are two a s surrounded by circular icons with an arrow.

To create a cross section first draw a line on your floor plan that cuts through a section of the house for which you need to show cross section detail.
