How to draw through holes in CAD

1. Click on the "hole" function under the mechanical module

Hole. <>

Hole type. 3. Specify the hole insertion position. After clicking the left mouse button and determining the position of the front of the hole, specify the angle of rotation or the position of the end of the hole.

Note: Here, through-holes, countersinking-flat holes, cylindrical through-holes, tapered through-holes, threaded through-holes, and other through-holes are indefinite, and can be automatically extended to intersect the selected boundary after positioning.

Structural parameters. 4. Determine the direction and boundary

Specify the hole orientation and boundary.

1.(Top View) command:

circle

Draw a circle with a radius of 25.

2.Command: offset

The offset generates an inner circle, offset distance:

3.Command: region

Select the inner and outer circles to create 2 regions.

4.Command: subtract

Perform a Boolean arithmetic, select the entity or region you want to subtract from, and select the outer circle;

Select the body or region you want to subtract, and select the inner circle.

5.Command: ext

Select the region as the object and extrude it into a pipe with an extrusion height of 120.

6.command: view

Enter left

Convert to left view.

7.Command: circle

Press the F3 key to open the snapping function), select the center of the circle at one end of the round tube, draw the circle as the center of the circle, and the radius of the circle is 20.

8.Command: region

Select the circle you just drew as the object and create 1 region.

9.Command: move

Press the F8 key to turn on the orthogonal function), select the newly generated region object and move 60 to the middle of the tube.

10.Command:

extSelect the newly generated region object to extrude into a cylinder with an extrusion height of 120.

11.Command:

view input front

Convert to front view.

12.Command:

move: Select the newly generated cylinder to move to the intersection with the tube.

13.Command:

subtract

Perform a Boolean arithmetic,

1. First of all, open the CAD software on your computer, mine as shown in the figure, after opening the interface is as follows, the interface will be different in different versions, which does not affect the operation, 2. Then you can draw a three-dimensional board, which will be convenient for reference, as shown in the figure below, 3. If you want to punch holes in this board, you can draw a circle in the position of this board to punch holes, which is the so-called punching, 4. Create the drawn hole as a region, stretch it downward, as shown in the figure, 5. After selecting the difference function, Choose to subtract the circle with the rectangle, and the figure will come out, done.

Draw two concentric circles.

The outer circle is the nominal diameter of the pin hole (i.e., MXX), and the inner circle is the inner diameter of the thread (which can be obtained by checking the national standard).

The outer circle has a thin solid line, and the inner circle has a thick solid line.

The dimension line arrow points to the outer circle and is marked as "mxx" (unit: mm).

This method is often used on the mold, and there are more holes on the workpiece, the purpose of using this method is to better distinguish the type and size of the hole, and at the same time, it should be noted that the hole of the same size is filled with the pattern of the sample.

1. Open CAD and draw a hole in the interface. This is shown in the figure below.

2. The next step to search for late combustion is to select the annotation, as shown in the figure below.

3. Give us the size of the hole icon. This is shown in the figure below.

4. Double-click the size, enter v in front of the original size, and enter x10 in the back. This is shown in the figure below. The world is empty.

5. Select the size, Dan wheel and then select the GDT format for the text format. This is shown in the figure below.

6. Finally, the annotation can be completed, X represents the hole depth symbol, and V represents the tapered counterbore symbol. This is shown in the figure below.

1. Draw a curved cylinder. The base radius is equal to the top radius. Bury the Fiber God.

2. Draw a spiral, and the radius of the bottom and top surface of the spiral is equal to the radius of the cylinder. Sets the thread height. (can be adjusted in the perk) x explode helix.

3. Adjust UCS to adjust the UCS Z axis to the same direction as one end of the helix. The x-y axis is perpendicular to the helix.

4. Draw a small circle at one end of the spiral and generate a region.

5. Stretch the small circle according to the path, with the spiral as the path. Generate 3D spirals.
