Geometry type
| Info |
|---|
When converting 3D CAD objects in midasCIM to IFC, you can choose which type of geometry to convert. |
Curved member: Sets the geometry type to convert for curved members.
- Swept Area Solid: Converts planar profile to Swept shape along the curved line (recommended).
- Faceted Solid: Converts curved surfaces in the form of triangles connected by Tessellation method.
(Used when compatible with other software that does not support Swept Area Solid)
Rebar : Sets the geometry type that rebar objects are to be converted into.
- Wire Body: Extracts rebar objects in the form of curves. Polyline, Circle, Arc, Ellipse, Elliptic arc, and Bspline are supported.
- Swept Disk Solid: Converts a circle or pipe Profile into a swept shape along a curved line. Capable of a three-dimensional path. (recommended).
- Swept Area Solid: Converts a planar profile to a swept shape along a curved line. Capable of only a two-dimensional path.
- Faceted Solid: Converts curved surfaces in the form of triangles connected by Tessellation method.
(Used when compatible with other software that does not support Wire Body / Swept Disk Solid / Swept Area Solid)
Tendon: Sets the geometry type to convert tendon objects.
- Wire Body: Extracts tendon objects in the form of a curve. Polyline, Circle, Arc, Ellipse, Elliptic arc, and Bspline are supported.
- Swept Disk Solid: Converts a circle or pipe profile into a swept shape along a curved line. Capable of three-dimensional paths. (recommended).
- Swept Area Solid: Converts a planar profile to a swept shape along a curved line. Capable of only two-dimensional paths.
- Faceted Solid: Converts curved surfaces in the form of triangles connected by Tessellation method.
(Used when compatible with other software that does not support Wire Body / Swept Disk Solid / Swept Area Solid)
Primitive Solid: Sets the geometry type to convert basic solid geometry.
- CSG 3D: Converts into a solid shape that can be represented with several simple dimensions. Cylinder / Pipe / Sphere / Cone / Block are supported.
- Extruded Solid: Converts a planar profile to a shape extracted in a specific direction. Suitable for representing straight members. (recommended)
- Faceted Solid: Converts curved surfaces in the form of triangles connected by Tessellation method.
(Used when compatible with other software that does not support CSG 3D / Extruded Solid)
Template Section: Sets the geometry type to convert an object that has used the template section.
- Parameterized Profile: Creates an object using IFC's template profile. (recommended)
- Arbitrary Closed Profile: Creates an object in a profile that is closed with various types of lines (Polyline / Circle / Arc, etc.)
[Select Target]
Select the objects to export.All in Current Mode : Exports all objects that exist in the current mode.
Selected Objects Only : Exports only the selected objects.
[Tessellation]
Tessellation is a setting that affects the precision of the geometry exported by the tessellation method.
If you want to export more precise geometry by lowering the base angle value of Tessellation, you can change the setting in the direction of "Very Low → Low → Medium → High → Very High".
However, the more precise the geometry, the larger the size of the IFC file, so be sure to apply the appropriate setting for your purposes.
