XuFyan Posted August 14, 2010 Posted August 14, 2010 Autocad R14, determining angles ?? see the figure below, How to determine which is the correct angle to draw the line ?? i have drawn this figure using these Commands but these command are not drawing accurate figure as above because my angles are not accurate. Command: pline From point: 0,0 Current line-width is 0.0000 Arc/Close/Halfwidth/Length/Undo/Width/: @280 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @250 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @80 Arc/Close/Halfwidth/Length/Undo/Width/: @30 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @120 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @30 Arc/Close/Halfwidth/Length/Undo/Width/: @80 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @80 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: c and how to edit the width of a specific line from a single figure using pedit ??? i used pedit but whenever i change the width of a linthe width of whole figure changes.

nukecad Posted August 16, 2010 Posted August 16, 2010 As the 'legs' are equal (20x20) the angles are 45 deg. (45, 135, 225, 315) Ever heard of Pythagoras? This is basic geometry and you should have a grasp of this if you are going to be drafting. Quote
lpseifert Posted August 16, 2010 Posted August 16, 2010 You don't need to know the angles... @20,20 (or @-20,20 @-20,-20 etc.) You can't edit individual segment widths with pedit. With R14 if you want different widths of segments of a pline, you need to do it as you draw it (I think... unless R14 has Properties) Quote
rkmcswain Posted August 16, 2010 Posted August 16, 2010 You can't edit individual segment widths with pedit. Yes, you can. how to edit the width of a specific line from a single figure using pedit You have to go into vertex edit mode first, then "W" for width. ... unless R14 has Properties) No Properties. The precursor to Properties was DDMODIFY, but it does not provide access to segment width. You have to do it with ._Pedit. Quote
lpseifert Posted August 16, 2010 Posted August 16, 2010 You have to go into vertex edit mode first, then "W" for width. . Ya learn something new every day... not that I'll ever use it Quote
XuFyan Posted August 16, 2010 Author Posted August 16, 2010 how do you know the legs are 20x20 , the bottom line is of 280 length then why my command is not making a perfect figure Quote
eldon Posted August 16, 2010 Posted August 16, 2010 how do you know the legs are 20x20 , the bottom line is of 280 length then why my command is not making a perfect figure If you really look at the dimensions, you will see that the bottom length is 260. This is confirmed by adding up all the other horizontal dimensions. The dimensions give you all the necessary information if you read them correctly. Quote
XuFyan Posted August 16, 2010 Author Posted August 16, 2010 Thanks Eldon As the 'legs' are equal (20x20) the angles are 45 deg. (45, 135, 225, 315)Ever heard of Pythagoras? This is basic geometry and you should have a grasp of this if you are going to be drafting. how did you determine the legs are (20x20) and how did you determine the angles are 45 deg ?? i know the pythagorus theorem but how to implement it in this figure ??? (sorry ,i am asking very silly questions ) Quote
XuFyan Posted August 16, 2010 Author Posted August 16, 2010 Now here is my Code , but the figure is still not accurate. Command: pline From point: 0,0 Current line-width is 0.0000 Arc/Close/Halfwidth/Length/Undo/Width/: @260 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @80 Arc/Close/Halfwidth/Length/Undo/Width/: @30 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @120 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @30 Arc/Close/Halfwidth/Length/Undo/Width/: @80 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: _u Arc/Close/Halfwidth/Length/Undo/Width/: @20 Arc/Close/Halfwidth/Length/Undo/Width/: c Quote
eldon Posted August 16, 2010 Posted August 16, 2010 Now here is my Code , but the figure is still not accurate.---- Arc/Close/Halfwidth/Length/Undo/Width/: @20 ---- Arc/Close/Halfwidth/Length/Undo/Width/: @20 At the sloping sides, the length of 20 is the Hozirontal and/or the Vertical distance. You need to enter in the Hypotenuse length with the angle, OR put in the relative x and y lengths. Quote
XuFyan Posted August 16, 2010 Author Posted August 16, 2010 How to put relative xy length for slope ? Quote
eldon Posted August 16, 2010 Posted August 16, 2010 How to put relative xy length for slope ? @20,20 - and make sure that you put in the correct algebraic sign for the X and Y lengths. For 45° use @20,20 For 135° use @-20,20 For 225° use @-20,-20 For 315° use @20,-20 Quote
XuFyan Posted August 16, 2010 Author Posted August 16, 2010 Hey..i've done this before reading your p0st i just read this before reading your post http://www.cadtutor.net/tutorials/autocad/using-coordinates.php and done this myself Thanks Alot Quote
