Create Secondary Beam for ETABS
The Draw menu > Draw Line Objects > Create Secondary Beams in Region or at Clicks (plan) command allows you to draw typical infill (secondary) beams for an entire grid line space (beam bay) in a single click. The grid line space is defined by four adjacent intersecting grid lines. If there are existing beams already in the grid line space then the spacing and extent (length) of the secondary beams is based on the existing beams rather than the grid lines. The figure below shows an example of a grid line space and secondary beams. Note that secondary beams are not included on the grid lines.
Tips Hatch in AutoCAD
You can determine how islands, enclosed areas within the hatch boundary, are hatched using the three hatching styles: Normal, Outer, and Ignore. You can preview these hatching styles in the More Options area of the Hatch and Gradient dialog box.
Normal hatching style (the default) hatches inward from the outer boundary. If the hatching process encounters an internal boundary, hatching is turned off until another boundary is encountered.
If you hatch using the Normal hatching style, islands remain unhatched and islands within islands are hatched, as shown below.
Three Dimensional (3D) Views in ETABS
You can set a window to a three-dimensional (3D) view either by using the View menu > Set 3D View command or by clicking the 3D View button, , on the main (top) toolbar. If you use the menu command the Set 3D View dialog box is opened where you can define the view direction by specifying a plan angle, elevation angle and an aperture angle. All angles are specified in degrees. The view direction defines the location that you are standing at as you view the building from the outside.
Figure a below shows a three dimensional view of a building using the default view direction of plan angle = 225 degrees, elevation angle = 35 degrees and aperture angle = 60 degrees. Figures b, c and d illustrate how the plan, elevation and aperture angles are defined. Following the figure are definitions of the terms used in the figure.
Eye point: This is the location from where you are viewing the building.
Target point: This is the geometric center of the building.
View direction: This is defined by a line drawn from the eye point to the target point.
ETABS Tutorial : Mesh at Intersections with Selected Line Objects
The Intersections with Selected Line Objects sub-option of the Mesh Quads/Triangles At option for the Edit menu > Mesh Areas command works for three and four-sided area objects; it does not work for area objects with more than four sides.
ETABS Drawing Generator Tutorial
ETABS Drawing Generator generates DXF drawings. There are eight different types of drawings which can be generated. These are
Full 3D Model: This is the full 3D model of the drawing. All line elements (Columns, Beams and Braces) can be seen with their actual cross section details. The whole model will be saved in one drawing and drawing name may be chosen in Output DXF File Name text box.
Column Layout Plan: This drawing contain the column layout plan for each story Level. Columns are marked with there full cross section details on the drawing. More than one drawings may be generated depending upon the number of stories and their selection. Read more
