How to determine whether the file is 2D or 3D?
What I would like to code is this: I enter the DXF file, and as soon as I find the first line segment that contains a non-zero Z value, I return: "This is a 3D file". I am even willing to return a "2D" answer after inspecting the first dozen points or so. Given the callback architecture of the libra...

How can a DXF file be validated?
I am developing an application similar to the Windows Search. It performs a recursive search, looks for some items inside the DXF file and proceeds to the next. There may be hundreds or even thousands of files, so expediency is a must. My problem is that when confronted with an in invalid DXF file, ...

Re: Some basic questions about DXF files
Luckily, my universe of DXF files contain limited features and hence the application will only have to deal with the most common entities: - Lines - Text - Polylines - Vertices - 3-D Faces Furthermore, I ignore the Z dimension and am not doing any rotation. Please notice the results that I have so f...

Re: Some basic questions about DXF files
I modified the provided " test " application so it shows more details. I would like to better understand things like: - Polyline parameters: flags, m, n, number - Vertex bulge But, alas, despite having a sizable collection of DXF files. All of them have zero values in those fields (except for "flags...

Some basic questions about DXF files
I am attempting to develop a "dxf2pdf" application (I guess I don't have to tell you what it does :-) It is being written under Linux, but will eventually be ported to Windows. Note on my background : Luckily, back in school I took a Master's level CS course, called "Computer Graphics" (which I fina...

Re: How to retrieve the header properties of the DXF file?
The DL_CreationInterface::setVariable* handlers are called for those. E.g. for $ACADVER: DL_CreationInterface::setVariableString("$ACADVER", "AC1024", 1) Andrew: My only use for dxflib is to read DXF files, and the purpose of the function that you mentioned seems to be to write DXF files. I am simp...

Re: The ONE item that is missing in the distribution
Actually, dear Self, it is rather simple. Just add the following member function to the provided "test" utility:
Code: Select all
void
CreationClass::addText(const DL_TextData& data)
{
cout << "TEXT: `" << data.text << "'" << endl;
printAttributes();
}

Re: The Number of Layers is a matter of dispute
I just tried several of my files with QCAD, and it handles their layers correctly. So the problem is either dxflib - or that I don't know how to use it.

The Number of Layers is a matter of dispute
Please notice the attached files. Different applications report different number of layers.
In my experience, dxflib (and QCAD?) handle layers correctly, provided that they are named.

Heights and locations of TEXT entities are being coupled
Question: Are the heights and locations of 2 AcDbText entities supposed to be coupled? QCAD doesn't think so but a 3rd. party vendor says otherwise. How can I decouple them?? Another way to ask this question is this: In addition to the text group code 40, what other parameter (code, table, dictionar...

Does dxflib retrieve TEXT?
dxflib Version 2.5.0 I have tried the test application that is included in the distribution with FIVE different DXF files. All of them contain one string ("Hello World!"). The 5 files have the following versions: Hello-R12.dxf: AC1009 Hello-R2000.dxf: AC1015 Hello-R2004.dxf: AC1018 Hello-R2007.dxf: ...
