Thank you Thomas for replying so quickly, I'm fine when generating mapping and serializer, but the link is wrong when generating the kernel

And I set option(BUILD_SHARED_LIBS "Build IfcParse and IfcGeom as shared libs (SO/DLL)." NO)

Hi, I'm encountering some issues while compiling a dynamic link library (DLL). When compiling ifcgemo, there are frequent linking errors, but ifcparse compiles normally. I'd like to know how to resolve this. I've referred to solutions on GitHub https://github.com/IfcOpenShell/IfcOpenShell/issues/1029 and https://github.com/IfcOpenShell/IfcOpenShell/issues/3785, and here's my CMake configuration, I only need 2x3 and 4x3 , and I set lib .Should I set up anything else? And I have set the build type...

Thank you Thomas for your quick response and for getting up so early to work. I now understand that although it looks 3D, it actually only takes coordinates on the xoy plane.

Hello Thomas, I have a new question while learning about squeezing. I currently have an inclined two-dimensional plane, and I want to get a shape that is stretched along the normal of that plane. However, it seems to project onto the xoy plane first and then become inclined, which is not what I expected. Taking the code below as an example, it generates an inclined square, but if stretched along the normal, it should generate a rectangle with one side length of sqr(2) * 1000. //A slanted three-dimensional...

Thank you, Thomas. I understand my mistake now. I should not use the position of the shape to substitute for the position of the object. Rotating the shape's coordinates will affect the actual coordinates. I appreciate your efforts.

Hello, Thomas. I had some problems creating pitched roofs, and when I spliced together multiple pitched roofs, I found that their z-axis were messy. Here's my code. I'm trying to convert a custom model to ifc format. The parameters in the code are all taken from the model. Is it because there are no intersection points between them after the normals are set?

Okay, thank you for your reply, Thomas. I wonder if there are any other ways to create an equal-thickness arc wall knowing the center, radius and thickness, as well as the radian

OK，Thank you Thomas

Hello, I'm encountering some issues when trying to create an equal-thickness arc wall. In the IfcCenterLineProfileDef I expected, the two arcs are not parallel but intersecting. I'm wondering if there's something wrong with my usage method. Here is my code. Thank you for your help. IfcSchema::IfcTrimmedCurve create_arc(IfcHierarchyHelper<ifcschema>& file, double radius, double start_angle, double end_angle) { // center point IfcSchema::IfcCartesianPoint</ifcschema> center = file.addDoublet<ifcschema::ifccartesianpoint>(0,...
