[. . . ] The selected Shapes in the Main Drawing Area are cut by pressing this button and are placed in the Clipboard. You can press the Paste button to bring them back onto the Main Drawing Area. The selected Shapes in the Main Drawing Area are copied to the Clipboard. The Shapes placed in the Clipboard using Copy button or Cut button can be pasted in Main Drawing Area.

Opens Edit Shape Layout to locate the shapes by specifying coordinates and angles. The Shape Editor is used to modify the dimensions and properties of the current shape. Toggle Dims Toggles the display of overall dimensions of the Section in the Main Drawing Area.

Rotates the selected Shape by 90 degrees in the counter-clockwise direction. The alignment is done with respect to the least value of the x-coordinate of the first selected shape. The alignment is done with respect to the x-centroid of the first selected shape. The alignment is done with respect to the highest value of the x-coordinate of the first selected shape. The alignment is done with respect to maximum value of the y-coordinate of first selected shape. The alignment is done with respect to the y-centroid of first selected shape. The alignment is done with respect to the lowest value of the y-coordinate of the first selected shape. This may be used to hide gridlines for a clear view of the Shapes and the Sections in the Main Drawing Area. Opens the Paper Grid Size form which allows you to modify grid size and spacing. If Snap to Grid is activated then all 14 RISASection 1. 1 Application Interface Grid movements of the mouse are locked to the nearest grid. This includes drawing of shapes, moving shapes or resizing the shapes. For more precise control, you may modify the grid sizes, switch off the Snap to Grid option or use Shape Layout Editor. This will reset the view in such a way that the whole Section is visible with all shapes on the Main Drawing Area. This button will enlarge the view and you may then scroll using the horizontal and vertical scroll bars to any required view. [. . . ] Increase the Y coordinate of the rectangular shape to 26. 50 to account for a 3 inch metal deck and click OK. General Reference Manual 37 Examples 13. Click to print the current section or click desired. to build a report and click to save the file if Note You may adjust the stiffness of each shape/material by double-clicking that shape and changing the modulus of elasticity (the default for concrete is 3000 ksi and the default for steel is 29000 ksi). The property multiplier automatically adjusts itself and is the ratio of the current shapes modulus of elasticity with the highest modulus of elasticity of any shape in the member. You may modify the property multiplier in the Layout Editor (click ) and it will automatically modify that shape's modulus of elasticity (Note that if you are using a shape from the RISA Shapes Database that you can not change the default modulus of elasticity value of 29000 ksi). 38 RISASection 1. 1 Technical Support Technical Support Technical support is an important part of the RISASection package.
