How to find the center of CATIA tube

1. Unknown_Error

2. If it's a pipe, it's suggested to scan or rib it. Is the pipe just a simple pipe, and is there a water stop valve in the middle? Can I send you an engineering drawing and I'll help you to dect 4204461

4. The traditional method is to make coordinate points first, then input each point in turn with the bending line polyline, and then select the bending radius r of each bending. If all the input is completed and the bending radius is reasonable, the line will be finished

in the surface, scan, sweep, select the third item, and then there is a center line and radius inside, At this time, you select the line as the center, and then enter a radius, then you will scan out a pipe

select thickening in the entity, then select the pipe surface just made, then input the wall thickness, and then select the direction (thickening inward or outward). At this time, the pipe is finished

if you want to modify the direction of the pipe, modify the coordinate point, modify the inner diameter, modify the radius in sweep, and if you want to modify the wall thickness, modify the thickening value just now

I suggest that spline should not be used as much as possible, because it will bring inconvenience to the master of grinding tools when machining metal mandrel. It is better to use polyline, and the bending radius is easy to control

in addition, you can make lines in the space, end to end, and then use the space fillet function to make the bending radius. In short, the part of the line is to control the direction, and the part for space avoidance

scanning is to control the inner diameter, because this is the key size. The thickening part is to control the wall thickness, which is the same principle as extruding semi-finished procts in actual proction. So this drawing method is more close to proction

in addition, if there is a flaring at the pipe orifice, the scanning surface with small inner diameter should be made first, and then the pipe orifice part should be cut off, such as cutting 50 mm, and then the large inner diameter pipe should be made, and the minimum distance of straight section should be reserved, such as 30 mm, and the rest should be cut off, and the last part is the transition section. At present, the distance of transition section is 20 mm. Use the bridge in the curved surface, and finally connect all the surfaces with the join, and then thicken the whole. After thickening, use the chamfer command in the entity for the connecting part, and then the fillet can be inverted to make the flaring part smooth

generally speaking, there are so many pipes. Generally, the branch pipes are made separately, so are the tee and quick coupling. Finally, the assembly parts are made by one assembly.

5. Draw a circle with ribs + a line of vertical circle, just sweep it

6. Ha ha, I also want to ask this question. Later, I went through the toolbar and couldn't find such a command
I want to find the length of the pipeline. Later I found that I can change my thinking. There are two methods:
1. Extract the surface to measure the surface area of the pipe or use the function to find the area. Then I think that the cylindrical surface is expanded into a rectangle, one of which is 3.14 * D, and the other is the length, so the pipeline length = s / (3.14 * d), which can be calculated directly by the function
2. By using the command of reflection line, selecting (or preparing) the appropriate direction, and then extracting the pipeline shell, two reflection lines can be obtained, and the length of each line is approximately equal to the length of the pipeline, that is, the length of the axis
I don't know if you want this result or not. It's for reference only.

7. The first problem:
1. Since it is a data conversion, the side line you can see can be projected onto two perpendicular planes, and then the center line can be calculated by using the fitting command
2. The included angle should be the simplest measurement. The included angle of two spatial straight lines can be measured directly
3. There is no need to lengthen the hose when measuring its length, right?

8. 1 Add "space admin" in CATIA icon attribute, and many posts have an introction
& quot; C:\ Program Files\ Dassault Systemes16\ B16\ intel_ a\ code\ bin\ CATSTART.exe" - run " CNEXT.exe -admin" - env CATIA_ P3.V5R16.B16 -direnv " C:\ Documents and Settings\ All Users\ Application Data\ DassaultSystemes16\ CATEnv" - nowindow
2 Modify environment variables. Start the program CATIA P3 Environment Editor and assign the following two variables respectively:
catreferencesettingpath to D: &# 92; Program Files\ Dassault Systemes\ B16\ intel_ a\ resources\ The value of pprnavigator
catcollectionstandard is D: &# 92; Program Files\ Dassault Systemes\ B16\ intel_ a\ Resources
(I think the value given above is actually the path of the standard and setting folder, so I want to make sure that the above two folders can be found in this path. If not, I will create an empty folder in this path)
after ing the two environment variables, save them and exit. Click the CATIA icon to run and enter the administrator mode.

9. In the generative surface modeling mole, draw a line in the space, and then in & quot; Graphic attributes & quot; Change the line to the dotted line in the column. You can simulate the existence of this line, but also through the bold and color to more obvious display& quot; Graphic attributes & quot; Column can be right-click in the toolbar selected and then transferred out.

10. The voltage in Japan is 110 volts! So there must be some parts such as adding transformers in the machine. There must be something wrong there. But I personally think the authenticity of your microwave oven is questionable. My sharp microwave oven has been used for 13 years (almost every day) without any problem. If it's true, you can make a phone call according to the instructions
