Creating a Floor plan, Footing detail and Isometric view using AutoCad
AIM:
To Creating a Floor plan, Footing detail and Isometric view using AutoCAD.
INTRODUCTION:
Floor plan:
Floor plan is two-dimensional technical drawing to scale showing a view from above, of the relationships between rooms, spaces, traffic patterns, and other physical features at one level of a structure. Architects use floor plans as tool to design buildings. Later, they are described buildings to those involved in the construction process.
Footing:
Footing is a part of foundation which is constructed with concrete or brick work masonry & acts as a base to the floor columns & floor walls. The main function of footing is to transfer the vertical load directly to the soil.
Isometric view
A 2D isometric view is a flat representation of a 3D isometric projection. This method of drawing provides a fast way to create an isometric view of a simple design. Distances measured along an isometric axis are correct to scale, but because we are drawing in 2D, we cannot expect to extract other 3D distances and areas, display objects from different viewpoints, or remove hidden lines automatically.

PROCEDURE: Type the DS in command box & press enter. In snap & grid palette select snap type as isometric snap & click on ok, cursor changes to isoplane left or click on isometric drafting on status bar & make it on. Click on the ortho made on status bar to restrict directions to 90 & 30 inclined to x axis. Choose line tool & specify first point. Move the cursor up & type distance 0.15 & press enter. Position the cursor in left up, type the distance 1 in command box press enter. Position the cursor in downward direction, type distance 0.15 & press enter & choose the close option in command box. |
 |
|
Using F5 key change the isoplane left to isoplane top or change it by using isometric drafting setting of status bar. Again, choose the line tool & specify the first point. Position the cursor in right up direction type distance 0.3 & press enter. Position the cursor in left up direction type distance 1 & press enter. Position the cursor in left down direction type distance 0.3 & press enter. |
 |
|
Choose the copy tool & select the lines as shown & choose base point as A corner of first step. Specify second point as B. Repeat the same procedure for three more times & create five steps. |
