Description

TECHNICAL FIELD [0001] Device and method for electric cable 3D auto-modeling and storage media storing computer program thereof.

The present invention relates to a method for automatically modeling an electric cable in three dimensions.

Revit is a building information modeling (BIM) software. Currently, Revit's Mechanical Electrical Plumbing (MEP) does not support cable modeling. In addition, Revit MEP does not support automatic modeling of tray, conduit, and tray support based on the designer's input data, so tray modeling, conduit modeling, or tray support modeling are all done manually. Is losing.

However, cables are expensive enough to account for more than 30% of the total electrical construction cost excluding equipment, and the time required for cable construction is so heavy that it exceeds 70% of the electrical construction process, exceeding 50% of the total electrical modeling. .

Despite the heavy weight of cable construction and modeling in electric construction, it is not possible to calculate or predict the quantity of cables in Revit MEP, so efficient electric construction and cable modeling are not performed.

Then, the shortest distance point on the plane from the tray to the target load is selected and the conduit is drawn out, and the drawn conduit is modeled as a horizontal section up to the top of the load. When the load is a motor, model the vertical section up to the middle point for the LOP (Local Operating Panel), and then model the motor terminal box and the flexible conduit up to the lower part of the LOP. When the load is a panel, a conduit is modeled in the vertical section up to the top of the panel.
