Basic View/Zoom functions
The Graphical Editor provides several ways to control the display of the drawing in the drawing area. You can zoom to change the magnification or pan to reposition the view in the drawing area. All display control options are located in the “View” drop down and the toolbar.
The following options are available:
The “Regen” command re-generates all drawing entities using stored geometry information. This command is slightly time consuming than the redraw function.
You can quickly zoom in on an area by picking the opposite corners of the zoom window defining it.
After selecting the “Zoom Window” option, specify the opposite corners of the zoom window in the drawing area by dragging two points.
All zoom operations are stored. So, anytime, a previous display can be recalled using the “Zoom Previous” option.
“Zoom Extents” displays a view that includes all objects in the current storey at the highest magnification that will fit in the drawing area.
“Zoom Limits” displays a view that includes all objects contained within the active sheet borders at the highest magnification that will fit in the drawing area. Pan After selecting the “Pan” option, you can pan the drawing image to a new location by left clicking and dragging from one point to another. This function can also be achieved by depressing the scroll wheel on your mouse and then moving the cursor around the screen.
Zoom In (20%) and Zoom Out (20%)
“Zoom In (20%)” increases the magnification of the current view by 20% and “Zoom Out (20%)” decreases the magnification by a similar amount. This option can be used to quickly zoom in and out to the centre of the current view.
This function can also be achieved by using the scroll wheel on your mouse. The Zoom will be focussed on wherever the cursor is placed on the screen.
Several entity selection options are available to select single and/or multiple elements for editing. Only visible objects can be selected using one of the selection methods. The entity selection options are located in the “Edit” drop down and toolbar.
Available entity selection options are:
Select Entity Option
After clicking on the “Pick” icon from the Members Toolbar, a single element can be selected by simply picking a
point on the entity. To select a second, and further, object(s) you can press the CTRL key while picking entities successively. If a selected element is picked again, then it will be de-selected.
After clicking on the “Pick” icon from the Members Toolbar, multiple elements can be selected by enclosing them in a
selection window. A selection window is a rectangular area that is defined in the drawing area by dragging two opposite corners.Two types of window selection are available. “Select Entity (Window)” option selects entities that are entirely within the selection area. “Select Entity (Crossing)” option select entities within and entities crossing the edges of the selection area. “Select Entity (Window)” is performed by clicking and dragging from left to right as shown in video.
“Select Entity (Crossing)” is performed by clicking and dragging from right to left: By reversing the 1st and 2nd points in the diagram above, Axes “A” and “1”, Column 1C1, Beams 1B1 and 1B4 and Slab 1S1 would be selected.
Fence is a line that selects all entities that it crosses. To perform “Select Entity (Fence)” hold down the SHIFT key and drag a line that crosses all elements that are intended for the selection set.
This option is useful when a set of non-orthogonal entities are to be selected.
