Roof Tool Commands

These commands are used for designing roofs.

ROOF AUTOMATIC

ROOF AUTOMATIC [SHIFT offs] <wall>

It creates an automatic roof above the outer control of the selected walls. If you use the option 'SHIFT' you can set the location of the roof's reference line in the specified distance from the walls. The command opens a dialog where you can specify the attributes of the roof.

 

offs (real): distance of the roof's reference line from the outer control of the walls

wall (obj): a wall to include into the selection

ROOF SWEEP

ROOF SWEEP {SELCIRCLE $circ_def$ | SELARC $arc_def$ | $profile_def$  coord <wall>} ENTER

This command can be used for creating a dome or for creating a roof above the selected walls with a self-designed profile. By using the option 'SELCIRCLE' or 'SELARC' you can draw a circle or an arc to construct the dome with the drawn layout. When selecting no options first you have to define the profile, select its reference point and select the walls.

 

coord (point): the coordinates of the reference point

$circ_def$: definition of a circle. See it in the chapter Definitions

$arc_def$: creating of  a circular arc. See it under the command ARC.

$profile_def$: definition of a profile. See it in the chapter Definitions.

ROOF SINGLE

ROOF SINGLE <wall> ENTER coord1 coord2 angle ENTER

It creates a roof plane of which boundary will be the outer contour of the selected walls. The inclination of the plane can be defined. The height at the reference line will be the default.

 

wall (obj): a wall to include in the contour of the roof plane

coord1, coord2 (point): the endpoints of the reference line

angle (real): the angle of the plane

SECTION

ROOF SINGLE SECTION roof coord1 coord2 angle

This command is used for inserting a new plane into an existing one. To design the new plane, first you have to locate the reference line then define the angle of the plane.

coord1, coord2 (point): the endpoints of the new plane's reference line

angle (real): the inclination angle of the new roof plane

ROOF P3

wall (obj): a wall to include in the contour of the roof plane

coord1, coord2, coord3 (point): coordinates of the points

elev1, elev2, elev3 (real): elevation at the actual point

ROOF ADDNODE

ROOF ADDNODE <edge {coord | SPOLYGON $polyline_def$} > ENTER

This command adds a node to the selected edge of a roof. If you use the option 'SPOLYGON' you can insert a whole polyline. The inserting doesn't affect the structural geometry of the roof. (The beams won't be redesigned.)

coord (point): coordinates of the new node

$polyline_def$: definition of a polyline. See it in the chapter Definitions.

ROOF MOVENODE

ROOF MOVENODE <node coord> ENTER

It relocates the selected node of a roof. The relocating doesn't affect the structural geometry of the roof. (The beams won't be redesigned.)

 

 

node (obj): the node to be moved

coord (point): the new place of the node

ROOF DELNODE

ROOF DELNODE <node> ENTER

It deletes the selected node of a roof. The deleting doesn't affect the structural geometry of the roof. (The beams won't be redesigned.)

 

node (obj): the node of a roof which will be deleted

ROOF INTERSECTION

ROOF INTERSECTION roof1 roof2

The command searches for the intersection line of the two plain roofs, and places a construction line on it.

 

roof1, roof2 (obj): the intersection line of these two roof plains is searched

CLINE

ROOF INTERSECTION CLINE roof height

This command adds a line to the drawing where the selected roof reaches the given height. If the plane hasn't got any point on this elevation, nothing will be done.

 

roof (obj): the examined roof plane

height (real): the elevation where the line will be drawn

ROOF STRETCH

ROOF STRETCH <edge coord > ENTER

This command relocates an edge of the selected roof. The edge's endpoints will be moved perpendicular to the edge. Only works when the roof is not modified with node editing commands.

 

edge (obj): the edge to be moved

coord (point): a point of the new edge

CLINE

ROOF STRETCH CLINE <roof edge [ALL] coord> ENTER

It relocates an edge of the selected roof's reference line. The edge's endpoints will be moved perpendicular to the edge. If you use the switch 'ALL' all the edges of the roof will be shifted.

ROOF PROJECT

ROOF PROJECT roof1 {TRIM roof2| HOLE roof2| ONPLANE roof2 plane}

This command creates one roof from two intersecting roofs by projecting the first onto the second. The first roof has to be an extruded roof. The options 'TRIM', 'HOLE' and 'ONPLANE' define the mode of the projection: TRIM: the projected roof will be trimmed; HOLE: below the projected roof the plane will be cut (a hole will be created); ONPLANE: you can select the plane on which the another roof will be projected.
