Symptom:
Selecting Linear Template drop handles causes Microstation to crash.
Possible cause:
The line string copied into the file becomes corrupt or changes made to it that breaks a Civil Data Relationship rendering the Linear Template unusable.
Workaround/Fix:
Clean up the dropped elements.
Note: You can trace the dropped line string (the example is the Existing Back of Curb) to make a single line string or you should be able to just re-import the linesting from the topo rather than tracing. There may be parts of the dropped line string, as well as the remaining line string segment that can be difficult to remove as it caused several Microstation crashes . This could be because the first segment was a complex string and the following was just a regular line string. I used the Microstation Drop Element tool to drop these linestrings to delete them. Removing the segmented line string I found that the Drop Element tool should be set as shown below.
Note: It is my opinion the problem originated from the original existing curb line string. Fixing this line string will resolve the problem, but you will have to recreate the Existing Curb Linear Template.
