The round scale method in AutoCAD and editor skill (go up)

The circle is one often uses the figure with scale, using drawing board to have manual plot period, people profundity is experienced " not with custom, without in order to become circumference " truth. Using the CAD software such as AutoCAD to undertake a CAD today, the new thinking of the design, new method changed the traditional concept of people, article system introduced round in AutoCAD scale method and editor skill, the scale to simple circle passed the author to be studied for long, undertook thorough mining to the function of AutoCAD, his experience raises plot efficiency to have certain effect to personnel of large-scale project technology. When project technology personnel is using AutoCAD to undertake the project is designed, round scale method is the basic technical ability that must master. The author uses software AutoCAD R12, AutoCAD R14, AutoCAD 2000, AutoCAD 2002, AutoCAD 2004 and AutoCAD 2005 to pursue engineering design early or late, be discussed deep and fumbled all sorts of methods of scale circle and round line wide setting edit skill, apply these methods and skill to will conduce to the applied level that raises AutoCAD. One, round scale method and editor skill 1.

With " round " draw " round " (command: Circle, quick command: C) is in AutoCAD " plot " next pulling in menu, listed 6 kinds " round " scale method, summarize as follows: (1) use the centre of a circle and radius draw circle: The punctuation that use mouse takes plot to command, operate according to clew next; (2) use the centre of a circle and diametical draw circle: The punctuation that use mouse takes plot to command, operate according to clew next; (3) with deciding diametical draw is round at 2 o'clock: The punctuation that use mouse takes plot to command, operate according to clew next; (4) with deciding diametical draw is round at 3 o'clock: The punctuation that use mouse takes plot to command, operate according to clew next; (5) in order to decide radius and two graphs object are tangent draw is round: The punctuation that use mouse takes plot to command, operate according to clew next; (6) use the centre of a circle and radius draw circle: The punctuation that use mouse takes plot to command, operate according to clew next. Raise a question: Use the circle of scale of afore-mentioned 6 kinds of methods, all of to be not many justice line scale, it is a line wide the filament that is 0 element line is round, in AutoCAD R12 and AutoCAD R14 version, in condition column wireless wide toolbar is installed, must use special skill to turn into circle of filament of 0 element line 0.

5mm broad line is round; In the version that AutoCAD 2005 reachs after AutoCAD 2000, although wired wide setting shows, but show truthless, the line is broad show have enlarge appearance, in graphical object more graph face affects editor vision. Turn into circle of filament of 0 element line 0.

5mm; ③ chooses cirque with design of the Solid in Hatch command; ④ uses circle of fill of design of the Solid in Hatch command. 2.

With " cirque " draw " round " (command: Donut, quick command: Do) is in AutoCAD " plot " next pulling in menu, listed " cirque or fill circle " scale method, namely: Input Donut(or Do) command all right in the command, after the internal diameter that inputs cirque and external diameter radius, the center position of reassign cirque can. If want scale line wide for 0.

The circle of 5mm, editor skill has 3 kinds as follows: (1) use Donut(or Do) to command scale line is broad for 0.

One of 5mm round methods: Input the diameter inside cirque and overall diameter respectively according to clew, when just inputting overall diameter, want to add 1mm, can come true, see a picture 3. Graph 3 command with Donut draw is round (2) use Donut(or line of Do) command scale is broad for 0.

Of 5mm round method: Input the diameter inside identical cirque and overall diameter numerical value respectively according to clew, after using modification command Pedit(or Pe) choice cirque next, lose the carriage return after W all right in the command, be defeated again 0.

5 hind carriage return, can come true, see a picture 4. Graph 4 ① command with Donut draw is round; ② changes with W of Pedit order option 0.

5mm broad line is round. (3) use Donut(or Do) to command scale line is broad for 0.

Of 5mm round method: Input the diameter inside identical cirque and overall diameter numerical value respectively according to clew, use Offset(or O) order next, the deflection inside the setting is apart from 0.

5 hind carriage return, after the Solid design fill in using Hatch(or H) order next, can come true, see a picture 5. Graph 5 ① command with Donut draw is round; ② uses circle of the deflection inside Offset command 0.

5mm; ③ uses cirque of fill of design of the Solid in Hatch command. 3.

With " polygonal " draw " round " (command: Polygon quick command: Pol) is in AutoCAD " plot " next pulling in menu, listed " regular polygon " scale method, namely: After the command inputs Polygon(all right or Pol) commands, of will acquiescent setting setting of 4 edges form is the biggest 1024 edges form, perhaps install acquiesce setting of 4 edges form is 8 edges form. 0 element line fine polygon turns into 0.

The broad line that 5mm sets accurately is round, editor skill has 3 kinds as follows (watchful is: Use the circle of scale of this kind of method, print indication effect very pliable) : (1) fine polygon of 0 element line turns into 0.
