Hi Folks!
I would do like to help if is possible. I think to help to integrate object with database. For example a object line to MySQL, I don't know about If already this functions is working or in developement. I think is hard to do, but... not impossible like another CAD Systems. So, thanks a lot! []s, Janse Romero |

Janse,
yesterday I put this up on the GSOC page : http://wiki.librecad.org/index.php/GSoC_2012 However if we want to implement this properly we need to create a new 2D- kernel and a proper API for entity manipulation, addition and querying, we hope to find somebody with enough knowledge to create such a thing. The storage backend can then be made pluggable to store entities in various methods. One note though, MySQL wouldn't not be a good tool for storing there because there geospatial engine is limited in InnoDB (MyISAM is not recommended here for your drawings). And we need geospatial capabilities to properly query large datasets. Ries On Feb 27, 2012, at 11:44 PM, janseromero [via LibreCAD] wrote: Hi Folks! |
Hi Ries!
I a beginner in this project, I don't know yet how it persiste a entity DB. But, What I thought was to create a handle inside the entity, and to refer it to a database with metadata information.
For ex.: I have a line, but this line is a wall with many characteristic and typical information, as well as White, made by stone and cement. Or We have a point, and this point means a pole of light, and his cost was $xxx,xx.
Did you get it ? In this case, no matter if the database is a GIS or not, and if is a MySQL or not, the important is to connect a entity to a data dictionary. How to ? Save a handle attribute in the entity and making a pluging read that one and to connect to some DB and show which meta data (on data dictionary) is that.
Sorry, If I couldn't be clear. Regards, Janse Romero On Tue, Feb 28, 2012 at 10:31 AM, R. van Twisk [via LibreCAD] <[hidden email]> wrote: Janse, |

Janse,
I see what you are talking about but then we talk about BIM (Building Information Modeling/Management http://en.wikipedia.org/wiki/Building_information_modeling). And I think that LibreCAD is not ready yet for BIM because of the way LibreCAD works. For this to work we really need a proper 2D kernel that can handle both simple and complex geometries. For example you need to beable to answer questions as 'how many lights are in there room', or 'How many lights are in these area', But also think about other questions, not buildings but pipelines underground or fencing work. But also when you zoom in and out of the screen it needs to be possible to only fetch these entities from the DB that are displayed on the screen and you cannot do this without a DB that has geospatial capabilities. Sure you can hack in some DB work into LibreCAD but then it would be a one-off project that just a hand people would use and would die out because it's not maintained anymore.

Now, I understood you totally. So, I will study more the librecad codes.
And thanks a lot for your attention. []s, Janse Romero On Tue, Feb 28, 2012 at 11:20 AM, R. van Twisk [via LibreCAD] <[hidden email]> wrote: Janse, |

Hi Ries,
I still think support for native SVG file format as interesting, and I think we can add it to the idea list. I think you and rallaz understand CAD file formats better than I, so, it's up to your decision.

Dongxu,
I think we are going off topic here, but the need for SVG is not that high for a CAD tool. And ideally I would like to see this working through the plugin interface. For DWG I am working on that and realized that we need to extend the plugin interface to support this functions. So priority lies in the plugin interface I think :) Ries On Feb 28, 2012, at 9:40 AM, dxli [via LibreCAD] wrote: Hi Ries, |
Wow! Cool hardcode aditions... Thats the thing about open source...
Personaly, i think user base request of features should be considered more fondely, after all, theyre the ones to get to really use it.

Hello everyone!! You may add to GSoC list , "ttf font support". I'm not specialist , and don't know what the need to do this. Valber src.lgg.ru 28.02.2012, 17:31, "R. van Twisk [via LibreCAD]" <[hidden email]>: Janse, |

Valber,
we can support ttf through the ttf2llf tool. TTF has currently limited use though because of CAD.. Ries On Feb 28, 2012, at 3:12 PM, hsd8 [via LibreCAD] wrote:

Hello again! I converted the font to llf, but I don't understand how to fill it. screenshot http://src.lgg.ru/wp-content/uploads/2012/01/LibreCAD_ttf2lff.png our article about russian open gov.standard font : http://src.lgg.ru/2012/03/gost-type-%D0%B0-0/ Valber 29.02.2012, 00:28, "R. van Twisk [via LibreCAD]" <[hidden email]>: Valber, |
hi, the easiest way is to search the *.lff files installed by librecad, and copy your lff file there (with root/admin access). librecad should be able to use it. the same way works for lff in source code folder. thanks, dxli On Mar 9, 2012 12:21 PM, "hsd8 [via LibreCAD]" <[hidden email]> wrote:

The font and symbols look like outline, how can I get rid of the black hollows inside the letters? http://src.lgg.ru/wp-content/uploads/2012/01/LibreCAD_ttf2lff.png 09.03.2012, 21:59, "dxli [via LibreCAD]" <[hidden email]>:
