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.
Options
Select a point to place section
Specify a point
Note: The section plane displays dynamically
parallel to UCS XY-plane, through the cursor position.
Specify distance
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.
set clipping oN
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).
set clipping Off
Sets the clip display property OFF.
Note: Clip Display property can be changed
from the Properties panel.
Detail
Creates a Detail section type.
Based on an existing section
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.
Interior
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.
Scale
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.
Reflected ceiling
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.
