Geometry type
| Info |
|---|
When converting 3D CAD objects in midas CIM to IFC, you can choose type of geometry for each object to convert. |
Curved member: Sets the geometry type of curved members for conversion.
- Swept Area Solid: Converts to shape which plane profile is swept along the curved line (Recommended).
- Faceted Solid: Converts Shape of 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 of rebar objects for conversion.
- Wire Body: Extracts rebar objects in the form of curves. Polyline, Circle, Arc, Ellipse, Elliptic arc, and Bspline are supported.
- Swept Disk Solid: Converts to a shape which Circle or Pipe Profile is swept along a curved line. Capable of a three-dimensional path. (recommended).
- Swept Area Solid: Converts to shape which plane profile is swept along the curved line. Capable of only a two-dimensional path.
- Faceted Solid: Converts Shape of 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 of tendon objects for conversion.
- Wire Body: Extracts rebar objects in the form of curves. Polyline, Circle, Arc, Ellipse, Elliptic arc, and Bspline are supported.
- Swept Disk Solid: Converts to a shape which Circle or Pipe Profile is swept along a curved line. Capable of a three-dimensional path. (recommended).
- Swept Area Solid: Converts to shape which plane profile is swept along the curved line. Capable of only two-dimensional paths.
- Faceted Solid: Converts Shape of 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 of basic solid geometry for conversion.
- 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 Shape of 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 of an object that has used the template section for conversion.
- 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.
