Common shortcuts in CAD 3D?

1. Die-cutting! It's very simple, but it's generally not the ordinary kind of riding staples, glue-bound books, locking books, the opposite sex is generally a little more on-board books and pop-up books, annotate: riding staples is popularly said to be staples in the middle of the book, locking the line is to take the line in the middle to wear, the glue bound book is neither staples, nor use the line, it is glued on, the board book is mostly used by children, a thick hard feeling, the pop-up book is to open the book, there are three-dimensional patterns inside, Just like you said about flowers and grass (I have a pop-up book in my space), my ability to describe this text is limited, you can consult me at any time, pm me, and answer all questions.

2, this needs to depend on your intentions, Bu Lu PS is generally a printed file, but also need a die-cut file or something, it is best to have a three-dimensional renderings, ** business is also good to go to the white sample, while confirming the structure.

Generally, I think that the printed matter consists of two parts, 1 is the printed content, 2 is the structure, of course, the ordinary book brochure square line rectangular ones have a size, with length, width and height, the structure will naturally come out, relatively simple.

3, you said "when you do it is to make a flower pattern on a white background" is not rigorous, to the ** business, people will definitely ask you, where is this flower placed, in the center or left to the right and up and down? Right? So, there's a lot of structural uncertainty about this kind of thing, and the most rigorous process is:

Give the first business out of the white sample (the white sample refers to the posture that is not printed but the structure is the same as what you want, the advantage is to save money and fast), and then you confirm the structure, and then let the first business pass the structure of the knife line to you, and then you are putting the file content you designed on the structure knife line, you yourself confirm it, and then pass it to the businessman, he will then typeset and print according to your printing content, and then surface treatment, die-cutting or something, so that it is safe.

After talking about so many traces of the manuscript, I don't know if I understand it.

The steps of CAD 3D drawing are as follows:

1. Draw an ellipse 90*55.

2. Draw another ellipse 200*100.

3. The small ellipse is moved down by 28 heights.

4. Draw four R100 arcs, to connect the two ellipses, remember to use USC to draw.

5. Copy an ellipse 90*55 from the 200*100 ellipse 80 high.

6. Draw four R200 arcs to connect two ellipses.

7. Draw a point away from the small ellipse and move the trembling circle up 28 high.

8. Use USC to draw two ellipses intersecting with points and 90*55 ellipses.

9. Trim the two ellipses.

10. Cut it into four arcs.

11. Let's take a look at the wireframe of the overall brigade closure first.

12. Prepare to do lofting work, sample the following figure, and use the green line to guide lofting.

13. Lofting into an entity.

The first picture is not touched (the combination of spheres and cuboids will be discussed next to the rest), the second is destroyed, and the third is as follows:

How can I tell you this?

The first one is to draw a sphere, then a cuboid, a chakra, then a difference, then a box, and then a difference.

The second one draws a cone, and then draws the difference after the box.

The third is the union of two defeats, a cylindrical Hongtong.
