Things get complicated when that is not the case. I have a north/south route which mean my plan sheets will have north pointed to the Right. In order to keep my plan sheet coordinately correct(required for drafting notes that may use computed coordinates), my sheet file must reference the base using the Coincident to the sheet file and the boarder will be over-sized and rotated.
When drawing a line using a Custom Line Style with Point Components that have Rotation set to Adjusted in a Rotated View, I expect that the flip will occur at the vertical position. It does not. I then thought that the flip occurs independent of the view and with always occur at the North/South direction. This is also not the case. I tested a view that was rotated 10 degrees to the right. The flip occurs at 20 degrees to the right. I then tested a rotated view at 20 degrees. The flip occurs at 40 degrees. I then tested a view that was 90 degrees to the right(just as my plan sheets will be for this project). The flip occurs at 180 degrees. Since there are 2 flip points in the total 360 degree direction, this 180 degree places the line completely upside down, no matter which direction I draw.
This seem like the original software developer tried to compensate for the rotated view by subtracting the angle difference between north and the amount the view was rotated to the north direction so that the flip would always occur in the vertical direction, but mistakenly added the angle difference from north.
A work around for this bug is to draw lines in a view that is rotated the same amount from north, but in the opposite direction. In my case I want the view to be rotated 90 degrees from north to the right, but drawing my lines in this view will cause them all to be upside down. If I open up a view and rotated it to the left 90 degrees and draw my elements in this view, my lines will be right side up in the view that is rotated to the right.
A whole another problem arises when I send out my survey crew to locate my utility lines. When I import that data from Inroads Survey, the lines are all such that the flip will occur in the north/south direction, regardless of what views are open. This occurs when I view temporary Planimeterics, write planimetrics to graphics, or view surface features. I don't know how I will work around this one unless I plan to draw all the connections to the points that were surveyed.
There is a command called Change Direction which will work great for the lines using a Custom Line Style with Point Components that have Rotation set to relative. I can just open the plan in the view that I want and look for lines that are upside down, and change the direction. Lines that have Adjusted point components will still be upside down.
So the fix here is to change all the custom line styles so that all the point components are set to relative and not adjusted, and then just use "Change Direction". Not so fast. We have custom line styles that have both point components that label the line "SAN" and another point Component the indicates flow direction ")". If a sanitary sewer line was flowing left to right, the line should look like this :
----------) SAN ----------) SAN -----------
If the line was flowing to the left, the line should look like this
----------SAN (----------SAN (------------
I am not sure how to work around this one. If both points are set to Relative, then the SAN would be upside down when flow is to the left. If they are set to Adjusted, then the flow indication is incorrect. One way that I have come up with is that there are 7 letters that are the same upside down. They are HINOSXZ. Maybe if I use the letters SNS for Sanitary sewer and set the points to Relative, SNS upside down is SNS.
Now I am just a design engineer, which means I don't quite understand how everything in Microstation works. So I say to you, respond to this, give me your wisdom,and let me learn.
Thanks
