Step 21: Now start point of starting line and endpoint of the ending line will connect to each other, and your structure will close like this. If you want to close the structure, press the C button of the keyboard and then press the enter button of the keyboard. Now you can draw the line again like this. Step 20: Now, again, for decreasing the width of the polyline, take the Halfwidth option of the polyline line command again and follow the same steps as we did in previous just take the value of start width and end width as 0. Now you can make the number of the arc with an increased width line like this. Now take the midpoint of the arc than the endpoint for making an arc. Then take the Second pt option of arc option as we did previously. For this, take the Arc option from the polyline command option again by pressing a button on the keyboard and pressing the keyboard’s enter button. Step 19: You can also make an arc with this increased width line. You can make any structure with this line. Now you can draw a line with increased width like this. For increasing the width of the polyline, just take the Halfwidth option again and enter the value of start width, then press enter button of the keyboard and enter end width, then press enter button of the keyboard to make sure both values should be the same. Step 18: You can increase the wide of polyline in the continuation of any structure. Now you can draw the line again because we had taken the value of end width as 0.
Step 17: Now, when you drag the mouse cursor, you can draw the arrow-like structure and make a click to give the length of this arrow, or you can enter your desired value by keyboard entry method. I will give it a 0 then press the enter button on the keyboard. Step 16: Again, specify the end value of the halfwidth option from the keyboard entry. I will give it as 2, then press the enter button on the keyboard. Step 15: Now, give the start value of the halfwidth option by keyboard entry. For the Halfwidth option press, the H button of the keyboard then presses the enter button of the keyboard. Step 14: Now, let us understand the Halfwidth option of polyline command from options of this command. Step 13: And again, you can draw the line with this command like this. Step 12: And for leaving this arc option of polyline command, press L from the keyboard, then press enter button of the keyboard for back into line form of polyline command. Step 11: Now click again and again on a new point as the endpoint of the next arc, and you can make a number of the arc with it like this. Step 10: Now click on a point as the center point of the arc, then again click on another point as the endpoint of the arc for making it.
Step 9: Then select the Second Pt option from the list of options of this command for specifying the point of the arc, then press the enter button of the keyboard. Step 8: Now draw a polyline, then press the A button of the keyboard for the Arc option of this command, then press the enter button of the keyboard.
When you select it, you can see there is a different option of polyline at the bottom of the working window of this software in the parameters box of this command. Step 7: Now again, take polyline command for analyzing different parameters of it. So polyline gives you the number of the connected line segments in one shape of the structure. Now when you select both of them with a mouse cursor, you can see polyline will select in the single selection and show you different connected line segments, but if we see the pattern of line command, it will select one segment of the line pattern. Step 6: And draw the same pattern of the line as we draw with the polyline command. Take line command from the draw menu of the Home tab. Sample programs: 3DSolid TRIM and SPLIT commands.Step 5: Let us take line command and understand polyline more clearly. CheckInterference: Interference operations.ġ8.9. Sample Program: Part created by INTERSECTION.ġ8.8. Sample Program: UNION and SUBTRACTION operations.ġ8.7. Sample Program: Sections of a Sphere.ġ8.6. Sample Program: Polyhedra obtained by slicing 3DSolids.ġ8.4. This Chapter includes the following sections: 18.1. Section objects automatically created throug programming. Although, fine tuning their properties will require using the ActiveX interface. The definition of section objects is exposed as DXF group codes in the classical AutoLISP fashion, so it is possible to create and modify them using entmake/entmod. These section planes can be used to analyze models by activating live sectioning and to create section drawings. Section objects act as cutting planes through 3D objects.
