BIM BEAVER read IFC files, and display it as a 3D model, and inspect properties. And create or modify instances and create things for architecture. BIM BEAVER read IFC files written by other BIM software like Revit, Archicad and so forth. BIM BEAVER support IFC format 2×3, and 4. BIM BEAVER is a freeware.
About IFC file
The Industry Foundation Classes (IFC) data model is intended to describe building and construction industry data.
It is a platform neutral, open file format specification that is not controlled by a single vendor or group of vendors. It is an object-based file format with a data model developed by buildingSMART (formerly the International Alliance for Interoperability, IAI) to facilitate interoperability in the architecture, engineering and construction (AEC) industry, and is a commonly used collaboration format in Building information modeling (BIM) based projects. The IFC model specification is open and available. It is registered by ISO and is an official International Standard ISO 16739-1:2018.
1)The bottleneck of rendering was removed and rendering speed approximately doubled than the previous.
I found it that the some type of drawing lines in OpenGL was very slow. The application used the VBO objects and called the following OpenGL command to draw lines. It was the bottleneck. I had to use glPolygonMode to draw polygon edges.
::glDrawArrays(GL_LINE_STRIP, i, size);
2) I put new tabs in the ribbon bar because there was no room for putting on new command buttons.
A bug was fixed in the application regarding to 3D view. The program had to release GDI objects at the end of rendering, but the program hadn’t released the GDI objects. It couses the slowdowns on the rendering and the application finally shutdown. (The GDI object is programing term. it’s represent rendering resouces.)
I embeded the bug unintetionally when I repeatedly had refined the program structure.
1). The bug fixed relating to IfcStyledItem. The application couldn’t display walls by the specified color.
2). Added HyperLink command.
Relate hyperlinks with instances. Select instances. and press button ‘HyperLink’ . Input hyperlinks in the dialog. You can specify multiple hyperlinks to the selected instances.
Press the ‘Open’ button after selecting one of the links in the list. the application will open the hyperlink.
Please use the ‘Search’ command if you want to confirm all hyperlinks in the IFC file.
You can search all hyperlinks in the IFC file by the Hyperlink tab.
Please just press the ‘OK’ button, then you can see a list of them.
The Beaver creates a property set to relate hyperlink with structural elements in the IFC file when you use the ‘HyperLink’ command.
The search command searches the property set.
3.) Fixed to deal with ‘Select type’ in the property window.
Change types of the ‘Select type’. Please press the option. And then you can see a ‘Change a select type’ dialog. You can select a type by the combo box. If you select an entity type by the combo box, The ‘Create’ button and the ‘Select’ button become active. If you want to create a new instance, please press the ‘Create’ button. You will see ‘Add new instance’ dialog to select an entity type. If you want to select an existing instance in the file, press the ‘Select’ button. After displaying the ‘IFC explore’ dialog, please select an instance that you want.
4.) The bug fixed relating to redraw.
The application had crashed when you change geometrical property in the property window relating to the boolean operation.
5.) The bug fixed for the ‘LOGICAL’ type in the property window.
There is a ‘LOGICAL’ type in the IFC specification. The type can express ‘TRUE’, ‘FALSE’, and ‘UNKNOWN’. The application couldn’t deal with the type in the property window.
