angel Posted October 24, 2010 Share Posted October 24, 2010 Hi everyone, I have a little problem with polar array option - I think I'm not doing something right. A while ago I use this option to make the first attached picture, but now I need to do exactly the same and I can't get the same result - second picture Do you know how I can array the objects one next to another and not one above the other? PS: I coudn't find post with info about this situation! :/ Quote Link to comment Share on other sites More sharing options...
ReMark Posted October 24, 2010 Share Posted October 24, 2010 You have to know the angle your are going to fill (90 deg) and the number of blocks required (6) using the example immediately above. I don't see where you would have a problem doing this. Quote Link to comment Share on other sites More sharing options...
angel Posted October 24, 2010 Author Share Posted October 24, 2010 In the first example the objects shrink at the bottom and stretch at the top to fit correct to the angle without placing themselve one above the other! In the second picture the objects fill the angle, but they are placed one above the other! I want to do it again like in the first picture, but I don't know how! I was looking for some mark, but I didn't see it, I guess I'm missing something, but I don't know what! :/ Quote Link to comment Share on other sites More sharing options...
nestly Posted October 24, 2010 Share Posted October 24, 2010 I don't think AutoCAD can do that by itself. Could it be that you made one compressed section and arrayed that to make the curved section? or maybe you used a lisp? http://www.cadtutor.net/forum/showthread.php?34297-Duct-elbow Quote Link to comment Share on other sites More sharing options...
angel Posted October 24, 2010 Author Share Posted October 24, 2010 No, I'm new to AutoCad and I'm still exploring the easy and visible functions I'm still far away from using lisp Thanks Nestly, I didn't make compressed section, but this remind me, what I did! I used the array option only for straight lines, then I made couple of extra arcs and manually connected the crossed point (arc x straight line) with each other in desired view. Then just deleted the extra arcs (actually I start using fillet option for making this type of arcs) It's slow, but that the best I could do, with my knowledge for AutoCad Thanks for the answers Quote Link to comment Share on other sites More sharing options...
eldon Posted October 24, 2010 Share Posted October 24, 2010 You have to look carefully, but the shapes going round the array in the first picture are different to the shapes along the straight parts. So you could have used a different shape to array, or you could have drawn it from scratch quicker. In fact there are some lines that do not end up where they should do Quote Link to comment Share on other sites More sharing options...
angel Posted October 24, 2010 Author Share Posted October 24, 2010 Hahah I know it doesn't look very good if you take a better look at it, but at that time, that was enough for me Maybe this time I'll make it fits better Quote Link to comment Share on other sites More sharing options...
Starkvinna Posted October 24, 2010 Share Posted October 24, 2010 I agree 100% with ReMark. I made the following picture using these steps: ORTHO ON, OSNAP ON COMMAND LINE: LINE (chose point) "up" 5 @2.5 @2.5 @-5 @-2.5 @-2.5 [enter] Then I used OSNAPs to make the center line really quickly. Then I "window-selected" all 7 items COMMAND LINE: AR rectangular array 1 row, 4 columns row offset: 0.0000, column offset: 3.5355 (right-click to approve after clicking "preview") COMMAND LINE: LINE (chose top of right-side '5' line as starting point) @1.9134 @1.9134 @-5 @-1.9134 @-1.9134 Then I selected the far right 7 objects. COMMAND LINE: AR polar array Center Point: chose THE left endpoint on the top horizontal line shown in picture. obviously yours will differ. Method: Total number of items and angle to fill Total number of items: 14 (obviously I was doing this quickly, and yours will differ) Angle to fill: 90 (right-click to approve after "preview") Then I recreated the very first object on top and then selected the the top 7 items COMMAND LINE: AR Rectangular Array Rows: 4, Columns: 1 Row offset: 3.5355, Column offset: 0.0000 (right-click after clicking "preview" to accept) COMMAND LINE: TRIM [Enter] Then obviously it needs to be cleaned up, trimmed, etc. Hope this step-by-step helps you at least figure out what you did originally, even though it's a bit different.
