Hidden line removal of 3d files
1. The exportation of visible edges, in Microstation 95 with the Exact
method, is time consuming and it's quite impossible to use this method with
large and complex files (I have experienced more than a week cpu usage for
exporting a detailed 3d roof). The Fast method is quicker, but the result is
a low quality hln file that needs a lot of time to correct (even using a
great amount of memory and the highest precision) Is there any improvement
in Microstation SE (vs. Microstation 95) in the management (more speed and
quality) of hidden line removal?
2.Performing the hidden line removal, complex surfaces are often translated
into b-splines curves. These entities are very difficult to modify in the 2d
generated file (that always needs corrections) and don't seem to be affected
by deldup32 or the remove duplicate lines command of Triforma (the last
affecting only lines). Is there some way to translate them into lines or
complex shapes without losing informations? I have tried the drop b-spline
command but I lose data.
Thank's in advance for any advice, Mark.
