drew4748 Posted October 28, 2014 Posted October 28, 2014 Recently I had a lisp routine made up by another member. It creates an array like pattern which searches for attributes located in each panel and patterns the blocks accordingly. This typically couldn't be completed using just the array command as the spacing changes between areas. It does exactly what it is programmed to do, however I would like to make a few changes and am unsure as to how to go about this. I understand the following part of the code allows me to change the y value, which I have done numerous times, however I cannot find out where to change the x value. I have tired adding an x value (similar to how the y value is added) with no success. (list x_pointer (+ 49.0 y_value)) 1.0 1.0 0.0) I also am wondering where in the code the routine grabs the spacing from. It appears the routine is grabbing the spacing from the next area, not the area the block is currently in. Is there a way to change this? I have attached a picture of the CAD which shows the difference. In the top way the first spacing is actually the spacing of the next area, not the area it is in. The only way around this is to trick it by adding 2 areas of the same value in a row, which will then increase the number of ballast blocks. If anyone can point me in the right direction on how to change this I would be very thankful. ballast.lsp Quote
marko_ribar Posted October 28, 2014 Posted October 28, 2014 A drawing showing before and after processing of the routine will help us to maybe try to improve it... Also, you could have provided link with original thread... http://www.cadtutor.net/forum/showthread.php?88364-block-spacing-lisp&highlight=ballast Quote

Yes, I guess that would be much more helpful. Sorry about that. As you can see the blue zone has less spacing than the yellow zone. To get fist spacing of the blocks correct, 2 yellow zones have to be added, which makes me come to the conclusion that the routine is grabbing spacing of the next colour zone. Please let me know if you need anything else. test 2 (after).dwg test 2 (before).dwg Quote
marko_ribar Posted October 28, 2014 Posted October 28, 2014 Your blocks (before) drawing have wrong attributes specifications... If there is 1 ballast, then attribute has to hold only 1 value of spacing between X coordinate of insertion point of block and X coordinate of ballast block insertion point... If there are 2 or more ballasts in a row in single block, then attribute has to hold 2 or more spacing distances between X coordinate of block and X coordinate of 1st ballast, and then spacing between 1st ballast and next ballast (2nd), and so on... Or alternatively spacings between X coordinate of block and X coordinate of each insertion points of each ballast... So according to your (after) drawing : 1. Lower left block : - spacing : 0.0 - back : 0.0,510.0 2. Lower right block : - spacing : 147.0 - back : 7.0,920.0 (between ballasts) or 927.0 (clean spacing between block and 2nd ballast) 3. Upper left block : - spacing : 0.0 - back : 0.0,760.0 4. Upper right block : - spacing : 427.0 - back : 507.0 Quote

It seems like it works and spaces the blocks exactly as the value of the attribute is programmed, just it grabs the spacing of the area the ballast block is going into, not the area it is currently in. How would I change this? Also where would I change starting x value point; I typically do all the blocks using this routine, then grab them all and move them over to the appropriate cantilever. Sorry if I am misunderstanding what you said, I just thought I was starting to understand it, but now I am not so sure haha. Quote
marko_ribar Posted October 28, 2014 Posted October 28, 2014 I think that the routine "ballast.lsp" is only working correctly according to specifications of attributes of blocks by pure luck... With my advise, you wouldn't have to have not understandable code, you would have to insert ballasts according to each block no matter where in array of selection it occurs... IMHO, this mod. would save you a lot of trouble and you'll be sure that you have correct result... Quote

drew4748 Posted October 28, 2014 Author Posted October 28, 2014 So how would I go about modifying this to produce the correct result. So i ended up fixing the issue as to why it was "grabbing" the spacing from the next zone, a block was behind my colouring zones which somehow was throwing off the spacing. Now my next question is how can I move the insertion point over rather than the lower left corner of the colouring zone. Quote
marko_ribar Posted October 28, 2014 Posted October 28, 2014 I am glad you solved the issue, but I would do it differently like I described... As for changing blocks base point, you have this solved on Lee Mac's website... http://www.lee-mac.com/changeblockinsertion.html Regards... Quote

I want to change the insertion point of the lsp routine. I know how to do the y value, however I cannot figure out how to do the x value. Quote
