[connect] are lines or linestrings better for performance

[connect]

I have to import a large amount of data (~118,000 elements) into MicroStation from another design software. Within the other software I have the option to export everything as single lines or to join the lines into linestrings.

screenshot of total number of elements, showing breakdown of different element types.

Which is better for performance within MicroStation?

Thanks.

  • whats the other software as you may just use the import in msnt or even exref > merge ref or > select all >copy> detach

    It depends on a lot of things  ... can you purge or compress the original in its native format package before export / import can sometimes make more difference as no history or  ghost elements or unused styles and empty levels.. just for giggles what the file size and format...

  • the data is coming from 12D Model. The exported file from 12D is a dwg, which i then reference and merge into master. i don't think there's any ghost elements or unused styles or empty layers. 

    the file is a dwg that is 2523kb.

    I have the exact same work flow from 12D files, how ever I have found its better to select all and copy the ref contents into the active file , then I deselect and turn off the ref ( like to keep the path for history) over time I have found the merge can sometimes bring over bad elements from acad but the old  copy only copies good elements. (BTW Reference method the no's colours work better for me as it adopts the mstn colour table not the acad one rather than convert the dwg to dgn)

    I then run the compress all options.. ( this is what I always did in v8i before) so next time the file will process much quicker...

    Acad and mstn users often forget to purge or compress their files, I find the acad files copied thro to msnt  are often much smaller than the original acad files especially after compress...I've also noticed in general a lot of my acad fellow workers reuse and cad file rather then start new this can make huge difference to file sizes, doesn't apply to 12D output as should be template based and makes new files.. but running the compress is just good practice...cant hurt right..?
