Creates a BIM section plane entity (1) in the XY-plane of the current coordinate system (WCS or UCS), that has the view direction (2) in the negative Z-direction of the current coordinate system.
Note:
If dynamic UCS (UCSDETECT) is ON, the section plane aligns to the face of a 3D solid under the cursor.
BIM section entities are created on a dedicated layer: BIM_SECTIONS layer.
Methods
There are three types of BIM section entities that can be created using BIMSECTION command:
Plan section type: Displays a horizontal section plane.
Section section type: Displays a vertical section that cuts though the model.
Elevation section type: Displays the exterior elevation view.
Note: The BIM section type can be changed from the Properties panel.
Note: The GENERATEASSOCVIEWS system variable controls whether VIEWSECTION produces 2D drawings which are persistently associated with the source 3D model. If GENERATEASSOCVIEWS is ON, associative dimensions are updated automatically when the 3D model is modified and BIMSECTIONUPDATE is executed.
选项(O)
指定剖面位置
指定点
Note: The section plane displays dynamically parallel to UCS XY-plane, through the cursor position.
指定距离
Type a distance or specify a point.
Note: It is recommended to have Dynamic Dimensions (DYN) active. It allows to type the distance in the dynamic entry field.
Note: The section plane is defined through the point or at the specified offset from the first point. The section line is parallel to the X-axis of the UCS or dynamic UCS and through the point at the specified offset from the first point.
Note: Only the section line and the callouts of a BIM Section entity display. When highlighted or selected the section plane, section boundary and/or section volume display.
设置剪辑
Sets the clip display property ON.
Note: This option is set as default. If the Hot Key Assistant (HKA) system variable is ON, press Ctrl key to toggle clip display property off.
Note: Multiple sections can have clip display ON simultaneously. This property can be saved in a model view (see VIEW command).
设置剪裁
Sets the clip display property OFF.
Note: Clip Display property can be changed from the Properties panel.
详细
Creates a Detail section type.
基于既有剖面
Creates a Detail section type based on an existing section. The base rectangle of the detail section will be parallel to the section plane of the selected section.
内部
Creates interior elevations and a floor plan of a space.
Note: The BIM/Interior elevation property of a space is set to ON. Use BIMSECTIONUPDATE command to update the interior elevation.
比例(S)
Sets the Scale property of the viewport in the drawing file created by the BIMSECTIONUPDATE command.
Note: The default Scale is saved through the SECTIONSCALE user preference (default value is 0.02) in Settings dialog box.
天花板
Creates the plan of a ceiling projected onto the section plane.
Note: A reflected ceiling plan shows the size and location of light fixtures and other structures on the ceiling. The clip display property of a reflected ceiling section is OFF by default.
Grips editing
BIM section entities can be edited through grips, depending on their state.
Plane state:
Start grip (1) allows to move the section and the position of the Start callout.
End grip (2) allows to modify the orientation of the section and the position of the End callout.
Center grip (3) allows to move the section and the position of the Mid callout.
The arrow (4) flips the view direction.
Boundary State:
Midpoint grip (1) allows to move the section entity.
Corner grip (2 & 4) allows to deform the section boundary/ volume.
Midpoint grip (3 & 5) allows to stretch the section boundary/ volume.
Volume State:
(6) allows to move the top plane of the section entity.
(7) allows to move the bottom plane of the section entity.
