For the unprocessed casting surface, it is more reasonable to choose according to the casting fillet, for the processed fillet, it is more reasonable to choose according to the knife point valve, and for the processed fillet, it can only be poured by hand. If it is greater than the ability of artificial pouring, it will bring unexpected difficulties and be scolded by others. It is one of the taboos in design to unnecessarily process large rounded corners to make you look good. Others need numerical control equipment to satisfy your good wishes, and the boss will scold you to death.
As for the painting in drawing, the standard drawing board is usually used by hand, and the computer is very simple, so it can be exaggerated according to the actual proportion and effect.
Question 2: How can the drawings in the PROE drawing template be marked with inverted right angles, rounded corners are easy to mark, and right angles can only be marked with dimensions? 1. Use Show/Erase, and then select the reserved chamfer.
2. Use comments, such as: C 1 or 1X45.
Question 3: Should the fillet be trimmed in the main view of mechanical drawing? Do you draw and program yourself, or do a drawing file? If you don't draw, you can draw and program by yourself, and you must draw when you make a drawing file.
Question 4: How to draw a fillet in cad software can use cha command, manual drawing can use compasses, and two intersecting lines can draw a fillet. You can draw a circle with the intersection as the center and the radius of the fillet to be drawn as the radius, and intersect the two lines at two points. Then draw the vertical phase of the two lines at these two points, intersect at one point, and draw a fillet with this point as the center.
Question 5: The chamfering rules of mechanical drawing are not stipulated by the public, but prompted by the drawing software. If drawn by hand, the larger the diameter, the greater the chamfer, which is generally an isosceles triangle with a side length of less than 10 mm; The larger the part, the larger the radius of the circle. R is generally an even number of 4,6,8, 10. ....
Question 6: Should mechanical drawing draw fillet lines? Which group of views in the picture is right? It should be no problem. In fact, the fillet transition is very smooth and no lines can be seen. You didn't have to draw transition lines by hand before, and now you don't have to draw them by CAD. But now there is a transition line in the three-dimensional CAD drawing, which can't be said to be wrong.
Question 7: Are hand-drawn compasses such as R2 and R3 ok? Do you draw directly by hand? Command: REC RECTANG
Specify the first angle or [chamfer (C)/ elevation (E)/ fillet (F)/ thickness (T)/ width (w)]: f.
Specify the fillet radius of the rectangle:
How to draw the inner and outer chamfers of two circles in CAD drawing? What is the principle of hand drawing? 10 minutes 1. Fillet: Click Modify-Fillet, pay attention to the command prompt, enter "R", press enter, specify fillet radius, press enter, and then select two lines to fillet respectively.
2. Chamfering: Click Modify-Chamfering, pay attention to the command prompt, enter "d", specify the chamfer distance of the first side, enter "d" again, specify the chamfer distance of the second side, and press enter, then select two straight lines to chamfer respectively.
If you use the shortcut key in the toolbar or use the English command (f- fillet; Cha-reverse bevel) will be faster and more convenient to operate.
Question 9: Simple steps to draw a hook by hand. Brother, I suggest you open the help and think clearly for yourself. Your cross cursor is equivalent to a pen. If you want to do something, just click the corresponding button, such as "circle", and then follow the prompts.
Question 10: How to cut a picture into a circle with word? As far as I know, word can't solve it. I suggest you use PHOTOSHOP.
