World-coordinates from points 1-20  21-32

 Is it possible to see the absolute coordinates of the points? Thanks for your time. EDITED: 20 Dec 2017 by FRANZ Attachments:

 8748.2 In reply to 8748.1 Hello Franz, when you enable the object snap an snap the point with the cursor the coordinates are shown in the lower menu bar. Is it that what you mean? Have a nice day Karsten p.s.: First select a drawing function e.g. line or point

 8748.3 In reply to 8748.2 Cplane ->apply to all views, but that's temporary until u reset it ! dont think it's possible, all the math and calculation should be done from a starting point and that's world coordinates - that has to be constant, unchanged !

 Thanks Karsten and Cermotan_Tudor! Both possibilities work, so that I can teach an old CNC system new movements..... The shape should be round, but this can only be done by defining the points in the old TPA (Italy) program. Angles must be quantified for a tangential milling form. Is there quicker method to get the tangential angles from the program? I did it with contructing rectangels and angel measurement. But it helped me a lot to find the coordinates of the points. Thanks for your help. EDITED: 22 Dec 2017 by FRANZ Image Attachments:

 Dear Cemortan_Tudor! Thanks also for this solution, it`s a good feeling to be not alone. Attachments:

 8748.7 In reply to 8748.1 Hi Franz, There is a PointsCoordinates script, to show the three coordinates of a picked point in a javascript Alert window. Thanks to Michaels past help, the catenary2ptxyz script has code to switch between world coordinates and what I called catFrame. - Brian

 Hi all. Another way to measure the angle. Vladimir. Attachments:

 Thanks to Vladimir for the additional way of angle measurment possibility. Thanks all for the great help so far, but now I have a special problem, maybe someone here can give me a tip: My old "CAVACAD" runs under DOS and can only import *.0G and also convert DXF (Version R13) files to *.0G. Now I get these dxf (R13) files, which I import without any problems with my old computer -from 1997 (16 bit processor)- automatically convert into files of this program with the extension *. 0G. The CAD program can only read these files and display them as drawings. To be able to use "CAVACAD", which requires DOS, with the Windows 8.1 PC, I have installed "DOSBOX", and it works (almost) completely. The *. DXF files, previously created with the old 16-bit PC, in *. OG files can now also be imported and displayed under Windows 8.1. But if I want to import the same DXF file as on the old PC and convert it to *. 0G with Windows 8.1 PC with DOSBOX, I get the message:"Access denied" or "Violated protection". I have already shared access rights, shares and owners in the folder and file properties for "everyone". This error message only occurs with the DXF file, the same file that can be converted in the 16Bit environment without any problems. Does anyone have any idea, what might be the reason for this? I have to say, that all other functions of the old "CAVACAD" work fine with DOSBOX in Windows 8.1 I hope I have been able to explain this difficult matter in an understandable way.

 8748.10 In reply to 8748.9 Hi Franz, I've only used DOSBOX once, a while back to play an old game in Windows 7, so know little about the problem. For what it is worth, here is one link: https://answers.microsoft.com/en-us/windows/forum/windows8_1-security-winacc/no-administrator-rights-on-windows-8-or-windows-81/58575911-e009-408b-a6ea-f980d9295888?auth=1 Came across link to W8.1 version of DOSBOX: https://docs.google.com/document/d/1KEfB40UonLS5XfRw3k9Crii7YEUUxHqBX0xE8cSwh-s/edit - Brian

 Thank you Brian for your quick answer, I have tested your suggestions. Also the scan was not successful, everything is clean. I should add, that this failed import and the conversion of *. DXF to *. 0G in the "CAVACAD" also occurs without DOSBOX in newer operating systems like Windows 2000 and Windows XP. Only the old PC from 1997 with the old DOS and Windows 3.11 does not cause any problems. I suspect that since the 32 BIT systems a Microsoft addition has been added, which is not 100% compatible with the old "CAVACAD". But what? It's a pity that all of the Italian software developers seem to be retired. Or just want to sell only more new systems...? (TPA Milano). Because they prefer not to give any information about the old systems. Best Regards Franz EDITED: 20 Dec 2017 by FRANZ

 8748.13 In reply to 8748.12 Hello Franz, is the 0G file ascii or binary. If it is an ascii, could you post an example. By the way, if you draw a tangent to your curve and make an path array you will have your tangents very quick. Have a nice day Karsten

 Thank you Karsten. The members of this forum are much more friendly than the company from which I have bought a lot of machines for a lot of money in the last years... Unfortunately I am not so experienced in computer file-details, but I have the files 0G and DXF in the attachment. From TPA (Milano) I received the following answer today: "Good morning I'm sorry but we're no longer able to support this software regards Mauro Narcotini Direttore commerciale Italia mauro.narcotini@tpaspa.it" My answer to TPA: Dear Sir! We will take your attitude into account when purchasing a new CNC machine. I guess you can't say thank you. This is the difference between serious and dubious companies. Attachments:

 <<>> Thanks for the useful tip, Karsten. To my dispute with TPA, software developer of CAVACAD. Think they're mad at me now. Narcotini wrote: "Never contact TPA again." (Because the software is so old, and as a developer it is serious in his eyes not to waste any more thoughts on it). Better I don't tell my wife, because we have been married for more than 25 years:)..... Franz just alone, without TPA Attachments:

 8748.17 In reply to 8748.16 Hello Franz, It seems that my wife thought something like that about me after 19 years. Anyway sometimes it's better to go different ways;-) Did You thought about replacing the CNC controller. How many axes has the machine and what kind of axis motors? How is the machine controlled? Is cavacad (Is it pronounced cave cad?) only to create the file or is it also the controller software? The 0G file is a binary file. I hoped for you, that it is ascii with a gcode similar syntax:-( Have a nice day Karsten
