Connect LineElements by VBA program

Have you looked at the data clean up utility in MicroStation?  It can do under and overrun detection.  In the API I would look to the intersect methods and then adjust the vertices of the line element.

HTH,

I have checked the clean up utility - but this feature only finds the gaps - it does not automatically connect the lines.

I don't have an idea yet how to start with the intersection methods - which method are you thinking about?

Search for intersections in VBA help.

If you have accesses to Bentley Map, I believe the 'Topology Cleanup' tools will allow you to flag and repair gaps.

I finally got it done ...

I use GetIntersectionPoints to find all lines that have already got a connection to another line.

Then I compare the IntersectionPoint with the start- and endpoint of both of the lines and replace them with the IntersectionPoint if they are not equal and within an area of 100 units.

Afterwards I check mdlMinDist_betweenElms for all the other lines that do not have a connection.

If the Distance is less that 100 units I extend the lines (using Point3dFromAngleDistance).

At the end I have to extend those lines which have got gaps that are in the middle of the second line.

Works fine - thanks for your ideas!!

PS: I can upload my code if you are interested!
