Tutorial 14: R3-8 Signs

Transcription

1 Tutorial 14: R3-8 Signs SignCAD Analysis The sign above is a typical lane control sign created using the Lane Control Panel tool introduced in version of SignCAD. The above sign is composed of five signs in a multipanel arrangement, where alignments and spacing in each panel are independent of the other panels. Individual panels can be added or removed, and the multipanel adjusts to accommodate the change. 1 Start by going to File>New>Texas Department of Transportation, and pick OK. 2 Pick the Lane Control Panel tool and pick a point on the screen. In the Rectangular Panel dialog box make the following settings: Sign type: Standard Sign. The Panel color will default to white. Tutorials 153

2 3 In the Size tab set the width increment to 0.5 and the minimum height to 30. Other values can be left to their default settings. Check Enlarge to fit Row height. 4 In the Border tab uncheck Size automatically, pick trim corners, and set width, radius and indent to 0.75, and 0.5 according to the Texas standard. Also in the Border tab check Lane Marker, height =12, width = 0.75 and check on the right edge. 5 In the Spacing tab pick Space to Border. 6 In the Custom tab uncheck Right border. Then pick OK. 7 Your sign should look like the one below: (Preferences>Drawing scale has been set to 12 ) Tutorials 154

3 8 Pick the Select tool and <Ctrl>select the sign, and pick from the top Edit menu, Edit>Duplicate. 9 Right click on the new sign and pick Edit Data. In the custom tab uncheck Left border and pick OK. 10 <Ctrl>select the new sign and pick Edit>Duplicate three times more. To allow direct selection of the panels, go to the Preferences menu and pick Allow Panel selection. 11 Right click on the last panel that was created and pick Edit Data. In the Custom tab Check Right border, and in the Border tab uncheck Lane Marker. 12 With the Select tool (and with Allow Panel Selection now turned on) Select each panel and attach them together. Your sign should now look like the one below: Tutorials 155

4 13 Once panels are attached, go to the Preferences menu and turn off Allow Panel Selection so that it does not eventually interfere with the selection of objects placed into the panels for alignments and spacing. 14 Go to the Preferences menu, shown above. Hovering over the R3-8 arrows will expand to show the list of arrows. The list shows the arrow name and some of its parameters, for example the first one A2L ir=4.5, s=2 indicates that is arrow A2, left curve, inside radius is 4.5 and shaft is For this tutorial you will select the smaller radius and height and the 2.5 shafts. 16 Pick the following arrows one by one and place them into the workspace: BL ir=13.25, s=2.5(the ninth one down); the C h=18.875, s=2.5; the ONLY_4D; LR ir=4.25, s=2.5; the ER ir=5.813, s=2.5; and the UL lr=3.5, s= The arrows are shown in order selected below: Tutorials 156

5 18 Pick the Select tool, select ONLY and from the top Edit menu, pick Edit>Duplicate to create three more copies of ONLY. 19 Drag each of the objects one by one into their corresponding panels. The result should look like the one below: 20 Window select the entire panel and right click, pick Object Align Bottom, then while all objects are still selected right click pick Object Spacing, and set top spacing to 0, left and right to 0.5, and bottom to 2.

6 21 Your sign should now look like the image below. If Object Align and Object Spacing is grayed out, the Allow Panel Selection item in the Preferences Menu is probably still checked. Uncheck it and window select everything again. 22 The spacing was set globally when all objects were selected, however spacing of individual objects can now fine tune the spacing. When you created the first panel, you had set the panel spacing in the panel dialog box to object spacing and space to border. You then duplicated the panels to replicate the space to border. The U Turn arrow shaft is touching or overlapping the vertical line, as are the two ONLY s in the internal panels. This is because the right border is turned off and the line width is ignored. Therefore you will need to account for the line width by adding its 3/4 width to the object spacing. The image below is the object spacing for the U Turn arrow: Tutorials 158

7 23 Before continuing, right click on any panel, and in the General tab pick Edit multipanel, and pick Dimension as a unit, then pick OK to both dialog boxes. This adds an overall dimension, which must end up being on a 6 increment. 24 Right click on the ONLY below the straight arrow and set its right spacing to 1. Do the same for the ONLY under the long right arrow. Tutorials 159

8 25 The left straight double arrow can overlap the vertical line to its left, and can align to the top of the straight arrow. 26 Right click on the double arrow and set its bottom spacing to 4 and its left spacing to -1.5 to overlap with the negative spacing, as shown below: 27 The sign is now 74.5 wide, which can either be reduced to 72 or increased to 78 to accommodate the 6 size increment. Both sizes are shown below. Tutorials 160

9 28 The image below shows the image above with the arrange tool highlighted. The objects controlling the width of the sign are the U Turn arrow, the double arrow, the two ONLYS in the interior panels and the arrow and the ONLY in the right panel. The right arrow spacing is left unchanged as.5 left and right. Object Left Right U Turn Double ST ONLY.5.75 LRT ONLY.5.75 RT ONLY.5 0 Tutorials 161

10 29 The image below shows the image above with the arrange tool highlighted. Object spacing has been adjusted to achieve the 78 panel width increment by changing only the spacing of objects shown in the table below. Again the objects controlling the width of the sign are the U Turn arrow, the double arrow, the two ONLYS in the interior panels and the ONLY in the right panel. Object Left Right U Turn Double ST ONLY LRT ONLY RT ONLY.75 1 Tutorials 162

11 30 Individual sign panels can be pulled out of or added to the R3-8 multipanel. The arrangement and spacing of objects in each panel is retained. 31 The modified sign will need to be adjusted so that its overall dimension is in a 6 inch increment, and that is accomplished by understanding, as described above, which objects control the width of each panel.
