Traditional mechanical drawing is to imagine the three-dimensional shape of the parts, and then the three-dimensional model from all directions projection, generate the projection surface of the two-dimensional view, dimensioning and other annotations to generate basic two-dimensional drawings. The following figure.
But the shortcomings of two-dimensional drawings is also obvious, is slightly more complex point is not intuitive, the need for human correct imagination. If there are three-dimensional digital mode display, and can rotate, zoom, it is more intuitive to understand.
Now has the three-dimensional CAD software SolidWorks Auxiliary, realizes the 2d-3d transformation, produces the general three-dimensional numerical model is relatively simple matter. For designers from AutoCAD to three-dimensional software transition, SolidWorks This function easy to start, can help you to easily complete from AutoCAD to three-dimensional CAD software across.
0SolidWorks Introduction
SolidWorks is a powerful, easy to learn and efficient and innovative three-dimensional CAD system, can be mechanical design, parts design, mold design, assembly and engineering drawing design, consumer product design.
SolidWorks Company was founded in 1993, 1995 launched the first edition of SolidWorks95. 1997 SolidWorks Company was acquired by Reach (i.e. CATIA parent company). SolidWorks Company is committed to everyone that complex, advanced 3D CAD application of simple, civilian, so that most engineers can quickly start. SW company 100% into 3D CAD research, according to customer demand to provide a strong technical innovation, for engineers to integrate a comprehensive auxiliary system (CAE, etc.). The company aims to be a three-dimensional standard in the field of mechanical design.
The leap from 2d-3d is the reverse process of traditional mechanical drawing (similar to Fig. 1, but the stereo model is generated from projection and film drawing). Input 2D sketches can be AutoCAD DWG format drawings, but also SolidWorks engineering drawings, or SolidWorks sketches.
This paper discusses how to implement 2d-3d conversion from AutoCAD drawing input to SolidWorks.
Principle: Many three-dimensional CAD/CAM software for the establishment of three-dimensional model, is directly or indirectly based on the sketch (or "sketch"), this is particularly pro/e. and three-dimensional software sketch (sketch), and AutoCAD, such as two-dimensional drawing is similar (but the difference is that the former has a parameterized technology).
In the SolidWorks, it is to convert the AutoCAD drawing input into the SolidWorks sketch to establish the three-dimensional numerical model.
Basic conversion Process:
1. In SolidWorks, open the AutoCAD format file for input.
2. Enter the *dwg,dxf file into a SolidWorks sketch.
3. Turn the various views in the sketch into the front view, the top view and so on. The sketch will be folded into a suitable perspective.
4. Align the sketch.
5. La Shanki body features.
6. Remove or stretch other features.
In this conversion process, the main use of 2D to 3D toolbar, easy to convert 2d map to the number of models.
Take AutoCAD2004 and SolidWorks2005 for example, to see how to enter from the AutoCAD drawings into the SolidWorks:
