marko_ribar Posted May 4, 2020 Posted May 4, 2020 (edited) But sometimes, calculation of HATCH PAT file by using my method can be very long and I still haven't found a way to speed it... Recently I posted a question at theswamp : http://www.theswamp.org/index.php?topic=55999.0 and I implemented solution in my codes... Read carefully all defuns... You'll see that I coded two global variables for getting partial results of calculations... So routine can be interrupted, but then you should save results into files... The goal is to make hatch by combining all saved *.txt files of *ll* variable... So firstly you apply fist (c:func1), then second, then third and so until you apply all in order I coded them... When you want to continue after interruption you should load *slsthand* global from saved file and repeat procedure on DWG you opened again or not... *slsthand* variable should be smaller after some data had been calculated... You do this all to the end... Finally you combine *.txt files of *ll* variables... Sometimes you can start HATCH generation and you waited long, but then again if DWG is not suitable (SNAPS were wrong or HATCH to complex with dimensions) there can be situation where after interruption you check !*ll* and it returns nil... So in this case you should avoid creating HATCH... Routine and DWG still not suitable for the task... So better save PC and electrical energy for something more useful...

marko_ribar Posted May 10, 2020 Posted May 10, 2020 (edited) I was brainstorming about this topic more, but unfortunately I only coded never ending stories... So my above posted code is for now the best, although it may give unreliable results with complex schemes for hatch generation... First one is combination of big code (iteration) and short one (recursion), but as it looks for very big ol - point list of rectangles origins, it never finishes...

marko_ribar Posted May 10, 2020 Posted May 10, 2020 (edited) My recursion (last code) worked for me as I mod. it slightly... But now it seems that my method of finding dx and dy is wrong... Routine did find dy minimal - that's for what is coded, but result was unexpected when hatched... So there is something what I/we don't quite know... In attachment as also in picture you can see buggy result... Regards, M.R. mr-hat.zip Edited May 10, 2020 by marko_ribar Quote
marko_ribar Posted May 10, 2020 Posted May 10, 2020 (edited) Neither is good for checking of minimal delta angle... Result is almost the same as with checking for min dy...

marko_ribar Posted May 10, 2020 Posted May 10, 2020 (edited) My latest findings are telling that problem with those codes - recursion is precision... Min dy should work, but when precision is greater (1e-8 => 5e-10), then routine goes deeper, but then is so slow that you can't wait to finish all operations during recursion... So still my best shot is firstly posted code with (while) looping... But yes, sometimes it isn't fully precise because of loosing speed (some checking is deliberately omitted)... Recursion version checks all... Edited May 10, 2020 by marko_ribar Quote
marko_ribar Posted May 12, 2020 Posted May 12, 2020 I've decided to improve more my main routine : https://www.cadtutor.net/forum/topic/70417-make-pat-files/?do=findComment&comment=565434 I added few more options for checking by delta angle and also I shortened main order of integer list if it was chosen secondary fuzz for which to check - else it can perform complete checking by all integer list gathered until main fuzz stops looping - rectangle origin is very close to XLINE angle of reference line with origin at minp... And that was all fine until I discovered that there were numerous lacks in my coding... I started calculation, and PC worked all until I discovered that LISP entered never ending loop... So I lost el. energy and time and only moments ago I finally cleaned it... So if you plan to use it, now is the time to copy+paste code tag to your *.lsp... Sorry for delay, but I didn't noticed bugs earlier... If there is still something wrong, and you discovered where was the bug, please help us to make it better as much as possible... I am using this routine now seriously and I don't want to think that it may fail at some point - AutoCAD calculated fine, but slow and BricsCAD fails, but I don't have too complex drawings for now so I am satisfied with AutoCAD job... Some results ACAD though can't present, but BricsCAD can, so both programs are useful in some ways and I hope you'll use routine well in your workflow... Regards, stay well, M.R. Quote
marko_ribar Posted May 13, 2020 Posted May 13, 2020 I've found one more lack... Now you can copy+paste the code... M.R. Quote
marko_ribar Posted November 6, 2020 Posted November 6, 2020 (edited) I've decided to add 2 more routines that are IMHO very close to optimum for custom hatch pattern generation... They are *-cross.lsp and *-uprows.lsp... The second one is the one I am really proud of - only lack is it's not going into infinity with rows and there was a problem with horizontal lines which had to go infinitely, so there can be some lacks in interpretations, but I suggest then - avoid horizontal lines if you can in custom sample for generation of *.pat file...

marko_ribar Posted November 12, 2020 Posted November 12, 2020 (edited) Hi, its me again... I tried to improve my version from top of this page, but still it's good only for simple examples, for more complex it may even fail and break... Nevertheless, I'll post my latest version here - now I am using this instead of top page code... And yes there must be no interuptions with ESC - this works like normal routine... I've hardcoded fuzz of 1e-3, but sometimes you'll need bigger number like 0.1, or even up to 5.0 and sometimes it's good as is - haven't experienced when smaller value is needed...

marko_ribar Posted November 13, 2020 Posted November 13, 2020 (edited) Here is my revision of last posted code... Now crash under BricsCAD is very rare, but when small fuzz is specified CAD may encounter much more points for checking for calculating dx and dy - it won't crash as now there is no list making and checking is performed on the fly, but amount of points that are to be expected may be over 1e+6 - millions if not even more... So it can be terribly slow, but precision is better when small fuzz is specified... On simple examples it's good, but for more complex there is no other way than wait to finish calculations... And all this at what cost - just to make *.pat smaller and inf rows and inf columns... FWIW my version *-uprows.lsp is doing this in matter of seconds - precise, but bigger *.pat and limited number of rows... Anyway here is my revision, so who want it may use it, but be warned - I explained the problem... Number of checking points can't be reduced - I don't know how to do it - HatchMaker.lsp from 2005 is doing this on square 1.0x1.0, but I am afraid I don't know how to implement such algorithm on my very custom example w x h rectangular boundary...

marko_ribar Posted November 15, 2020 Posted November 15, 2020 Just to inform that I've finally updated my revisions of last posted code and as a gift I am attaching my *.pat file generated with this routine... Note that ACAD generated correctly *.pat and BricsCAD had lacks, but all in all it was just slightly slower in ACAD... Regards, M.R. sup.pat Quote
marko_ribar Posted November 18, 2020 Posted November 18, 2020 (edited) Here is my latest version that I am using also... It should be faster than lastly posted one - there is no grid points checking - that's why it's better and faster... Still sometimes ACAD can't display hatch even if *.pat is IMHO correct... I'll attach my version of *.pat file generated with this version on more precise superman-logo sample DWG... I think that this is as far as I can write to be as much applicable possible by using my method of smallest dy...

hugha Posted November 18, 2020 Posted November 18, 2020 (edited) Marko, AutoCAD requires .PAT file lines to be strictly 80 characters long or less. You may be able to comply by selectively reducing the output numerical precision. Note only X and Y coordinate precision can be safely reduced, other values best kept as exact as you can retain within the line length limit. hope this helps, Hugh Adamson www.hatchkit.com.au Edited November 18, 2020 by hugha Quote
marko_ribar Posted November 18, 2020 Posted November 18, 2020 Hugh, thanks for your info, I've updated all my codes - now line length is max. 79 characters, but that was not an issue with displaying my *.pat file... I'll reattached it with my mods. upon using my revised last code... Somethings different is the problem, and I don't know what... Anyway, thanks for your valuable input... M.R. sups.pat Quote
hugha Posted November 18, 2020 Posted November 18, 2020 Marko, The AutoCAD .PAT file specification requires an additional blank line at the end of the file. Your file does not contain that extra line. Add a blank line to the end of the generated file. The last 4 bytes within the file should be cr lf cr lf. hth, Hugh Adamson www.hatchkit.com.au Quote
marko_ribar Posted November 19, 2020 Posted November 19, 2020 (edited) If I leave it like it is my *.pat file ends with 0D 0A... If I add last blank line it ends with 0D 0A 0D 0A... But in both cases it does not help with my sups.pat file I attached... With *.pat generated with reduced precision geometry it displays, but point is that precision should be as much good as possible - the problem with it is IMHO just by finding data by routine - parameter k may be so big that routine can't finish in reasonable time - also fuzz should be bigger like I hard coded it 1e-6, if it's smaller 1e-10 or more 1e-14 CAD may never find common base point of translated bounding rectangle and ray with starting point at lower left point of bounding rectangle and direction like it is in reference checking line...

marko_ribar Posted November 26, 2020 Posted November 26, 2020 (edited) Here is my latest revision, but I suggest that you firstly look in *.pat file generated by this routine... Sample is more precise version of superman-logo - S letter sign... As you can see, ACAD is now capable to show pattern, but still there are plenty lacks... Also note that it took on my slow PC half an hour to generate *.pat (around 250 more precise lines)... Still IMHO this is much better when and if you come in situation to try to generate such patterns... Still snaps are even with this precise samples necessity, so watch to fix all lines before routine (look at the swamp and my "fix2dlines2snappts.lsp"...

3dwannab Posted June 22 Posted June 22 (edited) @marko_ribar, If I give a description of test in my trial of this and save the file to testpat.pat then this is what it outputs. *test, test 42.22114819,0.,0.,1126.26190814,1241.17287848 Instead of: *testpat, test 42.22114819,0.,0.,1126.26190814,1241.17287848 Notice the first name proceeding the * must be the same as the file name. Currently it's putting the description for both. Edited June 22 by 3dwannab Quote
marko_ribar Posted June 22 Posted June 22 What happens if you type description : testpat and save file as testpat.pat P.S. I know this is old topic, but still I rarely use the code... Generated *.pat files are somewhat bad and produce undesired results... *.pat file must be very simple to make routine give desired output... Quote
