+- Solving issue: Connection between isolation box and parallel traces
 ### 08/13/2019
 - Rearrange the package and draw the path directly on original drawing from old roco
-- drawing structure:
-- ![](journal_media/dwg_structure.png)
 
 - dsn module placement match:
   - instead of getting pin locations from old roco. set pin location based on footprint when user place modules
   - Reason: 
     - 1. no mechanical design needed for pins (especial will turn it to cross cut anyway)
-    - 2. make sure the electrical board design and drawings will be consistent
-    - 3. easier to do drawing post processing (dealing with traces and isolation boxes)
+    - 2. make sure the electrical board design and drawings will always be consistent
+    - 3. easier to add new electrical components
+    - 4. easier to do drawing post processing (dealing with traces and isolation boxes)
 - Completed: a cross cut will be drawn at pin locations and that is automatically read from circuit design. The package will only need to load module once when design circuit

 - Draw isolation boxes and connect one edge with parallel traces without causing open circuit (fail)
