Who has the shortcut key for CAD 3D modeling? Seek a more comprehensive one .

The command is: extrude.

A shortcut is an alias for a command. The second part of the file defines the command alias. Using Notepad or any texter that saves files in ASCII format, users can change existing aliases or add new ones.

Other shortcuts:

1. F1: Get help;

2. CTRL+B: Grid snap mode control.

3. F2: Realize the switching between the drawing window and the text window.

4. DRA: radius annotation.

5. F3: Control whether to realize automatic object snapping.

6. DDI: Diameter annotation.

7. F4: digitizer control.

8. or hole dal: align the annotation.

9. F5: Isometric plane switching.

10. Dan: angle annotation.

If you want to use CAD's 3D space for modeling, then switch the space first. Many novice friends who have just learned may not know, the following is the content I brought about how CAD enters 3D modeling, I hope you can gain something!

1. Select the "AutoCAD Classic" drop-down menu in the CAD menu bar.

2. Select "3D Modeling" and click to go.

1. Double-click to open AutoCAD2012 software;

2. Click on "Sketches and Notes" at the top of the software to switch to 3D foundation;

3. Click "Top View" in the upper left corner of the drawing interface to switch to "Southwest Isometric", and the 3D drawing interface can be opened.

Personally, I think that there is no shortcut to creating a 3D model or entity based on CAD drawings, that is, 2D drawings. Because 2D graphics may also have mistakes, it may be difficult to rely on other software to directly generate 3D models based on 2D graphics (including incorrect expressions), and even if they can be generated, they may not be satisfactory.

On the contrary, it is possible to generate two-dimensional graphics through functions such as CAD plane photography. Because of the three-dimensional graphics, you can intuitively see the errors of the solid model and correct them in time. Two-dimensional graphics, because of their different expressions, such as sections, local sections and other means of expression, directly generate three-dimensional, inevitably misidentification.

However, if you have a two-dimensional drawing, according to the relationship between the three views, such as size, and shape, you can draw a three-dimensional diagram more easily and quickly, copy a certain face of a view to another place, trim it to a closed shape, and make it one"faces", and then determine the size of the face according to the dimensions of the other views"Stretch height", you can make an entity that is stretched out with this face, of course, specifically"Stretch, loft, rotate"To make entities, it will vary from diagram to diagram.

Personally, I think SW software is easier to use as 3D.
