Re: dimensions reading between librecad and other softwares

Hi,

if this cause draftsight to ignore the dimensioning, it is a problem of draftsight. The DXF reference says, that leading blanks have to be ignored. If there are no blanks, there is nothing to ignore and it should work anyway.

So I've downloaded and installed the free Autodesk TrueView DWG 2014 to see what the inventor of DXF format says. And it opens the LibreCAD DXF without problems. But be warned, the download is about 260MB and .NET 4 is required.

From my point of view I can't find a problem in LC now. First of all we have to finish LC final release before we care about other CAD software oddities.

Thanks anyway for your investigations. Just carry on!

Hi cantcode,

The spaces (blanks) are only for readability, and to set the file more BIG.

An ascii dxf file are pairs of code/values separated for \n (carriage return)

Hi Claus,

The exported DXF using CADEMIA 4.0 is version 2004.

I have access to AutoCAD, I opened your files (except nanoCAD because it fails)

Attached a screenshot with the result. See window title for the file name:

@Rallaz
I do not understand what you are talking about, do you mean that Autocad read dimensions?


@All
Hi, I have notced that dimensions of LC version1 are read from others cad, (a9cad, qcad up to now) so maybe you could restore the dimensions' programmation strings of LC 1.03.
p.s. if you will that keep the tick arrow option!




Bye to all

Hi Claus,

Remember that not speak english ;-)

About my previous post:

The author of the DXF specifications is Autocad then, so that is what I use to verify compatibility.

The capture that I added is to compare with LCinput.jpg (in your attached zip)

Same result opening in LC & Autocad:
Cademia, librecad12, qcadce205

Diference in decimal places ( controlled by DIMDEC, a dim variable not implemented in LC):
Drafthsight, librecadmaster.

Not equal (diferences in DIMGAP & DIMTIH):
qcad31

The nanocad file can not be open in Autocad.

Conclusion, LC only fails a bit opening qcad31 files, and 2 are because a uninplemented parameter.


Opening LC master in other CAD softwares:

Cademia can't open and Autocad yes, seems a problem of Cademia. (You have used zoom->all ? )

librecad 1.0.2 & qcad ce 2.0.5 is Ok.

Drafthsight, nanocad & qcad 3.1, opening some LC drawing in Autocad the result is similar,
on open the file dimension not are regenerated, instead are used *D??? unnamed blocks.
To force regeneration (in Autocad terminology)
select all, move from 0,0 to 10,0
select all, move from 10,0 to 0,0

This problem about use *D??? are present in dxf saved with LC 1*, LC master & qcad CE

Cheers,
Rallaz

Hi Claudio,

I added a patch solving *D??? issue.

Can you test if the dimension are shown in draftsight, nanocad & qcad3.1 trial ?

To test are required a LC compiled at least in 2013-Oct-02

Cheers,

Anyway. Just explain and I'll be happy to do it!

Hi Claus,

please find an actual Windows build from last night here:
http://download.librecad.de/LibreCAD-2.0.0rc2_c3be8043-Installer.exe

This installer contains a version with Rallaz's latest changes.

About Windows nightly builds, this is still in progress. We have a sponsored server, but need a Windows license to run the builds. Until this is done, feel free to ask me for latest master branch builds for Windows.

What about using ReactOS or wine instead of win or will this not work?

I don't think so, cause (as I heared) new features will be added after the 2.0.0 release.
