ADA Ramp Designer Command

Command Licensing and Default Menu Location The ADA Ramp Designer command is part of the RPS Modeling Toolbox Elevates 2D ADA ramp linework to 3D using min max design slope specifications. Labels lines with elevation and slope values for checking purposes. The command handles both single and dual ramp scenarios. Single or Dual Ramp Selection: Select whether you are elevating linework for a single or dual ADA Ramp configuration. Scale: XX.X - Change Plot Scale The labels that are created to display the elevation and slope values for the elevated lines will typically be drawn in Sheet Units i.e. if the Plot Scale is 50 and the Text Height is 0.08 Sheet Units then the text will be 4.0’ high on the drawing once the linework has been elevated. You may need to change the current displayed Plot Scale to a different value in order to get the correct text sizing i.e. Change plot scale to 10 to get a text height of 0.8’ on the drawing. Click the Change plot scale button to change the value that is currently displayed to the left of the button. Command Process and Calculation Method: The elevate process requires that you select an already elevated curb line, one or two pairs of 2D ramp lines (the left and right edge of the ramp(s)), and the 2D landing pad of the ADA ramp configuration. The command then elevates the ends of the ramp lines to the curb elevation and utilizes the settings defined in RPS Settings (see below) to determine the optimum slopes of the ramp lines and the associated elevations for the ramp line ends and the landing pad corners. The calculation method starts with the ramp line that has the lowest elevation at the curb. The command then applies the “Ideal Ramp Slope” parameter from RPS Settings to determine the elevation of the other end of the ramp line and the elevation of the landing pad. The elevations of the other corners of the landing pad are then determined using the Ideal Landing Pad Slope from RPS Settings. This then determines the elevations for the 3 other Ramp lines to complete the computation. If any of the ramp lines or the landing pad, fail to fall within the Min / Max Ramp Slope, or Min Max Landing Pad Slope ranges, the elevations are adjusted up or down, until all slopes fall within the defined criteria. The lines are then labeled using a Text Style and Layer defined by RPS Settings. Ramp Slope Settings: The ADA Ramps of a sidewalk at an intersection crossing have a Minimum Slope %, a Maximum Slope %, and an Ideal Slope % that falls somewhere between the Min and Max values. These three values are defined here in RPS Settings. The Ideal Slope is used as a starting value for a ramp calculation, and after all ramps are computed, can be adjusted up or down automatically such that all ramp lines fall within the Min / Max slope definitions. Landing Pad Settings: The ADA Landing Pad (at the top of the ADA Ramps) of a sidewalk at an intersection crossing has a Minimum Slope %, a Maximum Slope %, and an Ideal Slope % that falls somewhere between the Min and Max values. These three values are defined here in RPS Settings. The Ideal Slope is used as a starting value for a the ramp landing pad calculation, and after all ramps and landing pad are computed, can be adjusted up or down automatically such that the ramp landing pad lines fall within the Min / Max slope definitions. Layer: Select the layer onto which you want to place the slope annotations that are created by the command on completion of the calculations. Text Style: Select the text style that you wish to use for the labels that are created by the command on completion of the calculations. Select curb line: Select the 3D curb line for the ADA Ramp to tie into. The line needs to be already elevated. **Select Ramp Pair 1: (single and dual ramp configurations) Select the first ramps edge lines. These should be a pair of single 2D lines. **Select Ramp Pair 2: (dual ramp configurations only) For dual ramp configurations, select the second ramps edge lines. These should be a pair of single 2D lines. Select Pad: (single and dual ramp configurations) Select the ramp landing pad polygon. This should be a single closed line that has no elevation. On selection of the landing pad, the computations happen automatically, and the text labels for the ramp lines and landing pad will be displayed. Results pane: The command will display any results, passes or failure information into the Results pane of the command. Need the ADA Ramp Designer Command?
