SAP2000 – 03 Draw Commands: Watch & Learn


SAP2000 has many drawing tools to
facilitate modeling and this tutorial will demonstrate a
number of them most models are constructed using either frame objects or area objects we will start with the draw
frame command with this command we can draw frames
anywhere when in a planer view of the model a right-click will lift the pen but will leave you in
the draw mode you have the option to snap to grid but again you may draw anywhere in a planer view you can also
draw in a 3d view but the starting and ending points must snap to another
item such as grids or end points and the like if we tried to simply start the frame
in space the point snaps to the origin you must
also snap to end the frame there are a number of drawing controls
available including horizontal vertical parallel
to angle and others the letters in the
parentheses indicate the hotkey letter to activate
this option if we hit the H key while drawing the line will be
horizontal no matter where the cursor is similar
controls available if we hit the V key or A note that the angle is forty-five
degrees and L which draws a fixed-length object
clicking the set select mode button exits the
draw mode a quick draw frame command allows us to generate a frame on a grid
with a single click or on a number of grids by using a
selection box once frames are drawn there are a number of ways to edit and
modify them one way is to right-click on an endpoint
which brings up the point information form select the location tab and double-click on one of the
coordinates this displays the joint coordinate form where you may edit the end point location you may also move an end point by
selecting it and going to the Edit menu edit points align points command if we select the align points to X-ordinate
option with 0 the endpoint will be shifted over
to the y-axis the set reshape element mode command also allows the geometry to be modified with this command simply select and
hold down the mouse button on the frame object to move it parallel or select the member and grab one of the end points to
stretch and rotate the line next we will trim off the segment of the
line that extends past the intersection point we do this by selecting the line
to be trimmed the endpoint on the side to be trimmed and the line to be used as the trim line next we go to the Edit edit lines

trim/extend frames command and select trim frames the quick draw braces command allows for the generation of bracing with a single click in regions bounded
by grid lines to create secondary beams select the
Quick draw secondary beams button and click in a region bounded by grid
lines the orientation may be in the
y-direction the x-direction or in a direction normal to the edge
nearest your click this last option makes quick work of
adding miscellaneous framing next on the list of drawing tools are the area objects the draw Poly
areas command allows us to draw our completely
arbitrary polygons where we can use snaps or no snaps to lay
out the geometry the draw Poly areas command has the same
drawing controls for edge control as the frame objects did including the
horizontal and vertical options note that again
these options may be selected using the hotkeys hit the enter key on the keyboard when
your area object is complete the draw rectangular area command allows us to generate rectangular
areas by clicking dragging and then clicking
again to finish drawing these area objects may be
any size and although these objects were drawn as
rectangles using the Set reshape element tool allows
us to easily change their shape or move them the Quick draw areas command allows us to
create area objects in regions bounded by grid
lines with a single click or in multiple regions by windowing throughout this tutorial we have had the snap to point and grid
intersections option on however there are many other snap to options
available including snapped to ends and midpoint snap to line intersections snap to perpendicular projections
whereby a line can be drawn perpendicular to any existing line and snap to lines or edges this concludes this tutorial on drawing
commands
