Did not come for several months to post the forum, first of all to the new and old friends who asked good. Made a post today on how to do mechanical parts Axonometric map plane. The application of practical work experience do.

Preparations:

1, basic knowledge of machinery:

Mechanical parts in the axonometric view, a round that is elliptical, and can be divided into three directions (see Figure 1), the length of elliptical axis ratio of 12.2:7, which is a constant, we must remember! This proportion of ellipticalmost real Axonometric map, which is equivalent to three-dimensional effect. Size according to the actual size of the remaining drawing!

2, drawing environment settings:

Right-click the bottom of the computer interface "to capture the object", and then left-click the dialog box "Settings ...", the" axis tracking "of the" incremental angle "to 15 degrees (or 30 degrees) can. Other settings, such as "linear," "target tracking" and other preferences may be, with them.

3, part drawing materials: For painting ready drawings Axonometric map (see Figure 2).

The beginning of the drawing:

1, first draw a circle Φ10 oval (see Figure 3), then the drawing can be scaled into different diameter of the elliptical circle. Yo skills easily! Since then the drawing, it is necessary to use an oval, please copy the first step to zoom in and out of the ellipse and rotation.

2, in accordance with the laws of mapping to identify a axis (see Figure 4)

3, one copy to the axis of the ellipse endpoint (see Figure 5)

4, according to their amplification with Φ28 oval pore size (ie, 2.8 times enlarged) (see Figure 6)

5, repeat step 3, copy to the axis of a ellipse endpoint (see Figure 7)

6, according to diameter size Φ68 amplification oval (that is, 6.8 times enlarged) (see Figure 8)

7, the thickness of paint components 10 (= 12.5-2.5). Simply put the two oval to move along the axis 10 (see Figure 9) to (first choice, then click the move button, and then type distance data), for cylindrical tangent, figure, first draw the long axis of the ellipse, tangent to the other oval cited.

8, cut off surplus lines or non-visible lines (see Figure 10)

9, repeat Step 3, copy the oval to the icon location (after the offset of the center of a circle 10), left for parts of the stage, note: there may not be visible line, in fact, can be judged based on experience is not visible. Not visible on the line is not drawn. (See Figure 11)

10, according to plans to enlarge the size Φ42 and migration 2.5. Note: If the left is not visible level, you do not need to draw. Red oval icon that left parts of the stage, not visible but was deleted. (See Figure 12)

11, continue to draw the three small holes (see Figure 13) (Note: according to the actual size of the passage, it is very important! Figure auxiliary line)

13, cut off the extra lines and make up the painting parts Φ38 left visual contour. This complete (see Figure 15)

14, Fig Axonometric other direction is as follows: (see Figure 16)

Special parts of the painting details:

Rounded down, but at right angles to the painting with thread

Rounded down, the best oval in accordance with the direction of drawing, and sometimes easier to directly use the "round down" tool, but not true.

Down at right angles, according to the size map, can not directly use the "anti-right-angle" tool.

Thread painting, pitch shift by using an oval can, do not have to pay attention to only the general meaning of that thread them.

Painting pipe parts: a round in the light of the corner of intersecting line painting will be a little more realistic.

Off-topic: In practice, I used two-dimensional three-dimensional axonometric axonometric plans to replace the benefits plan is: a small file; convenient layout; the same document in different parts quickly insert; parts and components is also a good connection between the mapping . Disadvantages: complex painting gear.

Mechanical drawings in axonometric map drawn to facilitate understanding of parts operatives shape, capable of slightly lower knowledge map, a small error rate. We generally use the plan + axonometric diagram form.
