3D Modeling 14: Easy Way of Getting a Section From a 3D Model

1 Comment Mar-23-2009 | Posted by Orhan Toker | Printable Version | Level |

Dear Friends,

Throughout this article, we are going to learn how to get a section cut from a 3D model easily. Erhan has written two detailed articles about getting section cuts earlier. (Live Section 1 and Live Section 2) Also, SOLDRAW and SOLVIEW commands, which I am going to explain in more detail soon can be used for getting section cuts.

Yet, getting a section by using SECTION command is easier than those two commands. We can get a section by a single move like FLATSHOT command

Fig.1

Let us now get a section cut quickly from the model seen in Figure 1 by using SECTION command. The command processes as below:

Command: _section

Select objects: 1 found

Select objects:

Specify first point on Section plane by [Object/Zaxis/View/XY/YZ/ZX/3points] <3points>:
Specify second point on plane:
Specify third point on plane:

First, you have to select the object from which you want to get a section cut. Then you have to define three points that the section passes. Pick the points in the order shown in Figure 1.

The next step is taking out the section object from the model because Autocad draws the object inside our 3D model. Our job is easy:

Command: _move

Select objects: l
1 found

Select objects:
Specify base point or [Displacement] <Displacement>: Specify second point or <use first point as displacement>:

Take out the section object by using MOVE command.

Fig.2

I am going to mention other section plane options of the SECTION command later. You have to wait for ‘3D Plane Designation’ article.

May it be easy.
