ifcplusplus's Issues

We Need non const method IfcPPModel::getMapIfcObjects(), or metod IfcStepReader::readStreamData(std::string&, shared_ptr<IfcPPModel>)

We need to load BIM model in two steps.

1) read IFC Header
2) read stream data.

Code example:

typedef std::map<int, shared_ptr<IfcPPEntity> > mapIfcPPEntity_t;
mapIfcPPEntity_t map_entity;
shared_ptr<IfcPPModel> ifc_model(new IfcPPModel);
IfcStepReader read; 
read.readStreamHeader(buffer, ifc_model); // 1)
read.readStreamData(buffer, map_entity); // 2)

After that, need to copy map_entity into ifc_model. 

mapIfcPPEntity_t::iterator it = map_entities.begin();

for(; it != map_entities.end(); ++it)
{       
    ifc_model->insertEntity(it->second);
}

Why do it? This code may be cause of a low performance loading.

I offer 2 ways to resolve this issue;

1) Add a "non const" method 
std::map<int,shared_ptr<IfcPPEntity> >& getMapIfcObjects() { return 
m_map_entities; }

Then we can use this code:

read.readStreamData(buffer, ifc_model->->getMapIfcObjects());

2) Add a new method

void IfcStepReader::readStreamData(std::string& in, shared_ptr<IfcPPModel> 
model);

SI unit length metric without prefix should be valid

SI unit for metric length should be valid even if there is no "IfcSIPrefix" as 
it is optional. If it is not there then unit scale factor of 1.0 should be 
valid.

In UnitConvrter.cpp in function 
void UnitConverter::setIfcProject(shared_ptr<IfcProject> project)()
{
..
..
..
if( unit_type->m_enum == IfcUnitEnum::ENUM_LENGTHUNIT )
{
    if( si_unit->m_Prefix )
   {
    ...
    ...
     length_factor_found = true;  // Move this outside of this scope
   }

  length_factor_found = true;  // Should be here
}
..
..
..
}

}

Remove Boost from repository

Hi

Would it be possible to remove the boost library from the repository? I guess a 
lot of people who use ifc++ already have a boost version, so it would be easier 
to use it as an external dependency or something like that.

Thanks
Robert

IfcPPWriterSTEP::writeStream- std::ios::showpoint

What steps will reproduce the problem?
1.Create a step writer. 
2. check the .ifc file after the header there is unexpected number "16"



stream << std::ios::showpoint; // This will print out the value of the enum 
which happens to be "16"

should be 

stream << std::setiosflags(std::ios::showpoint)

Non VC-project files?

While the project seems to be set up to be platform independent, there are only 
Visual Studio project files available. It would make it easier for porting to 
e.g. OSX or Linux, to use CMake or qmake project files available.

Crash - regression from R20 to R27

What steps will reproduce the problem?
1. Open the supplied v12_extract.ifc file
2. Crash with IFCPP R27, not with R20 (R24 modified RepresentationConverter.cpp 
could be the cause?)

What is the expected output? What do you see instead?

IFCPPSimpleViewer R20 didn't crash (but didn't handle an opening), R27 crashes.

What version of the product are you using? On what operating system?

Using the github repo based on R27.

Performance issue

What steps will reproduce the problem?
1. During Loading some IFC files.

What is the expected output? What do you see instead?
Slow performance during loading IFC files and destroying 
std::map<int, shared_ptr<IfcPPEntity>

What version of the product are you using? On what operating system?

I use old version of ifcplusplus, that doesn't support C++ 11, because the 
project using Visual C++ 2008 compiler.
Project was tested on Windows 7 x64

Please provide any additional information below.

Hi, thank you for this library!

I tried to research the performance issue of ifcpluplus library. I'm using AMD 
Code XL 1.9.

1. I replaced std::map<int, shared_ptr<IfcPPEntity> to 
boost::container::flat_map<int, shared_ptr<IfcPPEntity> >. Also, may replace to 
boost::unordered_map<int, shared_ptr<IfcPPEntity> >.

std::map and boost::container::flat_map have the identical O(1) complexity, but 
std::map have the very big cache miss and memory allocations.

2. Also for boost::shared_ptr may to add some macros.

src\ifcpp\model\shared_ptr.h:

#ifndef BOOST_SP_DISABLE_THREADS
#define BOOST_SP_DISABLE_THREADS
#endif
#ifndef BOOST_SP_USE_QUICK_ALLOCATOR
#define BOOST_SP_USE_QUICK_ALLOCATOR
#endif
#ifndef BOOST_SP_NO_ATOMIC_ACCESS
#define BOOST_SP_NO_ATOMIC_ACCESS
#endi

BOOST_SP_USE_QUICK_ALLOCATOR - using for fast allocations.
BOOST_SP_DISABLE_THREADS/BOOST_SP_NO_ATOMIC_ACCESS - if using single thread for 
loading

I attached the edited version of ifcplusplus library. You can use it for the 
future versions. Thanks!

Dumb question -- building in Windows

I was trying to compile the library on windows, and I think that just setting 
the environment variables according to 
https://code.google.com/p/ifcplusplus/wiki/BuildInstructions won't be enough to 
make MS VS find the libraries. Is there some official additional steps for 
building?

What steps will reproduce the problem?
1. download openscenegraph and compile with MS visual studio express 2013
2. download cgal, qt etc
3. set environment variables like 
https://code.google.com/p/ifcplusplus/wiki/BuildInstructions and run visual 
studio and build solution

What is the expected output? What do you see instead?
VS complains about not being able to find include files. I added the 
environment variables to the project properties, additional include libraries. 
But when compiling SimpleViewer it still tries to find Qt under D:\lib\... 
instead of where I specified (C:\Qt\...). I can't find where to change this.


What version of the product are you using? On what operating system?
r25, on Windows 7 with MS visual studio express 2013

Please provide any additional information below.

The problem has been reproduced on two different PCs running MS Windows 7. Same 
fail. Also, the popup window doesn't say what point (STEP line number) the IFC 
parser failed.

IFC file attached.

Please let me know if you need more details.

Question about Carve's boolean problem

Dear Prof. Fabian,

I noticed that there are some problems in Carve's Boolean operation. I reported 
some issues to here:
https://code.google.com/p/carve/issues/detail?id=79


but it is not responsed for a long time. Could you please help me to take a 
look at it?

I noticed that when two models have very large size difference (for example, 
one is 0.01 meter and the other is 100 meters), the boolean operations would 
fail. Do you have any suggestion to solve this problem?


Thanks,
Tang Laoya

Feature Request: add STEP numbers next to each fail in the Read/Write IFC Tab.

I currently get an anonymized list of errors in the Read/Write IFC tab, like:

Error: convertIfcBooleanOperand problems in extrude: poly_data->points.size() 
!= 2*polygonal_boundary.size()
convertIfcBooleanOperand problems in extrude: poly_data->points.size() != 
2*polygonal_boundary.size()
convertIfcBooleanOperand problems in extrude: poly_data->points.size() != 
2*polygonal_boundary.size()
convertIfcBooleanOperand problems in extrude: poly_data->points.size() != 
2*polygonal_boundary.size()
convertIfcBooleanOperand problems in extrude: poly_data->points.size() != 
2*polygonal_boundary.size()
...

By knowing the STEP numbers, where each fail occurs, I could extract only the 
offending IFC snippets and attach them to future logs.

Thanks

Issue with a CSG IFCWALLSTANDARDCASE

Hello,
The attached IFCWALLSTANDARDCASE opens correctly in Solibri Model Viewer but 
converts to a huuuge wall when using IFCPlusPlus. I guess the CSG operation to 
stamp a side of the wall (see attached picture) is not correctly handled ?
Can you provide some hints (or a fix ? :-) ) to handle this problem?
Thank you in advance !
Sylvain

Feature Request: need for memory error handler when IFC++ fails loading big IFC files.

IFC++ loading the 288-Mb IFC file has been tested on two PCs. The file can be 
found at http://download2cf.nemetschek.net/www_misc/bim/DCR-LOD_300.zip

The first PC, with 16Gb of RAM, loaded and displayed the IFC file just fine, 
and the other with 4Gb of RAM never completed the loading and got hanging with 
no error messages.

The addition (or, fixing if already present) of an error handler signalling the 
memory issue while loading is needed.

Thanks

Missing definition in CMake files

What steps will reproduce the problem?
1. Compile Carve and Ifcplusplus


What is the expected output? What do you see instead?
No errors, but I get lots of compile errors. I think you forgot a CMake 
Definition. In the CMakeLists.txt of the folders Carve, IfcPlusPlus and 
IfcPlusPlusGeometry (and SimpleViewer I guess) you have the line after finding 
boost:

add_definitions(-DCARVE_SYSTEM_BOOST)

But this is missing the HAVE_BOOST_UNORDERED_COLLECTIONS defintion. So changing 
this line to 

add_definitions(-DCARVE_SYSTEM_BOOST -DHAVE_BOOST_UNORDERED_COLLECTIONS)

solves all boost errors.

In addition, in /Carve/src/include/carve/win32.h, line 24:
#  include <carve/cbrt.h>

gives also errors, as cbrt is already defined. I guess you have to move it 
below for an older VS version, or just remove it?

Last thing, somehow the libs are not created, only the dll files. I changed all

ReaderWriterIFC requires IfcPPReaderSTEP header

The line 
https://code.google.com/p/ifcplusplus/source/browse/trunk/IfcPlusPlusGeometry/sr
c/ifcppgeometry/ReaderWriterIFC.h#55 causes a compile error because the 
ReaderSTEP is not included. 

Changing:

#include <ifcpp/reader/IfcPPReader.h>

to:

#include <ifcpp/reader/IfcPPReaderSTEP.h>

solves it

Some IfcProducts got added to osg::Group twice

What steps will reproduce the problem?
1. Load the file from Issue 17
2. Get the geometry generated as osg::Group, save as file
3. Look at the file using some other software

What is the expected output? What do you see instead?
The beams are added twice. Actually, the same node pointer is added twice, 
because when I rename one of them, the other gets renamed too.


What version of the product are you using? On what operating system?
r25, on Windows

Please provide any additional information below.
* There's a slight chance that this may be related to the cause of Issue 17. My 
guess is that when this file is loaded, both the product_shape 
(ReaderWriterIFC.cpp, Ln 505) and the product_switch_curves 
(ReaderWriterIFC.cpp, Ln 521) are valid.

IFC++ viewer

1) The colour of curve3D entities are not shown in the IFC++ viewer. 

2) IFC++ viewer does not have support for point,  
RepresentationConverter::convertIfcGeometricRepresentationItem() could we add 
case for Ifcpoint?


Thanks :).

Some IfcWalls have their normals inside out

What steps will reproduce the problem?
1. Load the attached IfcOpenHouse.ifc file in IFCPlusPlusViewer
2. Turn on the back face culling 


What is the expected output? What do you see instead?

The walls with openings (?) have their normals inside out. IfcRoof, Slabs ... 
are OK (normals pointing out, not influenced by the back face culling)

What version of the product are you using? On what operating system?
r24

Make viewer optional

Hi

I see you added the Cmake files, thank you very much. One improvement would be 
to make the SimpleViewer optional, as I integrate IFC in my CMake build process 
by EXTERNALPROJECT_ADD. So as I have my own application and don't use Qt, I 
need a way to only build the framework. The easiest would be to introduce an 
option for the viewer. This would look like this in your root CMakeLists.txt:

...
ENDIF(NOT CARVE_BINARY_DIR)
message(STATUS   
"------------------------------------------------------------------------")

OPTION(BUILD_SIMPLEVIEWER "Build the simple viewer example applilcation" ON)

add_subdirectory (Carve)
add_subdirectory (IfcPlusPlus)
add_subdirectory (IfcPlusPlusGeometry)
IF(BUILD_SIMPLEVIEWER)
    add_subdirectory (SimpleViewer)
ENDIF()

Would it be possible to integrate this (or something similar)?

Thanks for the great work
