When close doesn't count.
Just because you have the best MicroStation users in the world doesn't mean they're perfect. How many operators are so careful that they make every single pair of lines (and arcs and curves) meet exactly?
The answer is darn few. Because a user who spent that much time trying to be that perfect could end up with low productivity.
Most real-life MicroStation users interject dozens of minor (or major) inaccuracies into your design files every day. The best users introduce less than others, but still, if you look, the inaccuracies are there.
Inaccurate line intersections are a very common problem. Two lines or arcs that should meet exactly don't. Maybe they overlap a bit. Or maybe there's an unwanted gap between them.
You may not easily see such errors on the screen, but when plotted they can become embarrassingly evident to you, to your boss and to your customers.
Intersection Fixer solves this problem.
Manual quality control is painstaking and expensive. Intersection Fixer cleans up sloppy intersections for a fraction of a human proofreader's salary.
Where do overshoots and undershoots come from?
Overshoots and undershoots are the result of imprecise digitizing (perhaps, the most common kind). Raster-to-vector converters can be another source of overshoots and undershoots.
Intersection Fixer will automatically correct overshoots and undershoots of lines and line strings in a MicroStation design file. If a line is too short to touch a line it should meet exactly, it is automatically extended. If a line overlaps a line it should meet exactly, it is automatically shortened. Since almost all design files have at least some overshoots and undershoots, Intersection Fixer is useful to the vast majority of MicroStation users, regardless of their discipline. Intersection Fixer is not just for mapping projects.
- Delete elements that are smaller than the user specified tolerance.
- Flag element endpoints to show what is cleanable or uncleanable.
- Interactive mode to control the cleaning process one element at a time.
How do I control the clean-up process?
Intersection Fixer accepts a parameter file. The parameter file tells Intersection Fixer several things:
- Which elements should be adjusted. Elements can be selected based on level, color, style and weight.
- Which elements should the above elements be compared against. For example, if you know that elements on level 31 are only annotation, you could specify that Intersection Fixer not compare against elements on that level. Elements to compare can also be selected by type, level, color, style and weight.
- The parameter file also specifies the tolerance to clean to. Elements that miss (overshoot or undershoot) by more than the tolerance are not corrected.
To take full control of the cleaning process as it happens, use the interactive mode settings and enter the interactive mode to clean one element at a time.
Intersection Fixer also cleans curves, arcs, and connected strings.
Intersection Fixer can also clean curves, arcs, and connected strings. In addition, this algorithm includes the ability to compare against arcs, connected strings, curves, ellipses, and complex shapes.
One of the most important features of Intersection Fixer is that it accomplishes the cleaning of arcs and curves without stroking them down to line strings. Stroking arcs and curves down to line strings is highly undesirable because it increases design file size, slows down redraws and makes design files display and plot with choppy straight lines instead of elegant curves. With Intersection Fixer, your design files retain all the intelligence, efficiency and grace they start with.
