Carto Rep for watershed subbasin boundary
I am trying to create a line carto rep for watershed subbasins. I have looked at the Desktop Help and done web searches.....to no avail. Maybe it is the prescription drugs (I had surgery last week) or the non-prescription drugs (I was a child of the 60's) but I can't get my head around the instructions. Could you please explain the process as if I was a 4th grader.
The symbol is part of the "FGDC Digital Cartographic Standard for Geologic Map Symbolization". The reference number is 26.7.2.
Mapping Center Answer:
Start by making the line symbol. Click Customize on the top bar menu then Style Manager to Open Style Manager. In your style (or another in which you have write capability) click the Line Symbols folder in the left panel. In the right panel, right click, click New > Line Symbol. In the Symbol Property Editor, change the Type to Cartographic Line Symbol. Here are the specs for the line symbol:
- Lineweight .425 mm
- Dash length 5.0 mm
- Dot diameter .45mm
- Spacing .5mm
Click OK to keep your changes and rename the symbol to 26_7_2 (or whatever you want).
Next apply the symbol to your features. In the table of contents, right click the feature class that you want to apply the symbol to adn click Properties. On the Symbology tab, use the Features – Single Symbol renderer and click the symbol patch. Select the line symbol that you created to apply it to the features in the feature class. Click OK. If there are no connections among the lines (intersections), you can stop here. You only really need to use carto reps if you want cleaner intersections since this happens to be a dashed line symbol.
Next convert the feature class to representations – note that your data need to be in a geodatabase in order to perform this next step. Right click the symbolized layer in the table of contents and click Convert Symbology to Representation. Zoom in to see some of the intersections. Are they to your liking? If not, then you may need to adjust the properties of the cartographic representations line symbol. To do this, right click the layer in the table of contents, click Properties and on the Symbology tab, modify the settings for the Dashes. You can also add additional control points to set how the lines join at sharper angles (in addition to the intersections).
Here is the online help topic that describes the Dashes and Add control points settings: List of representation geometric effects
