Hi Volker,
I am trying to repeat your presentation from last SIG
but I have to stop , because I dont understand ,how you made symmetry line/special node? and symmetry plane to mirror created BSplines from double tangented controllers
pls. see added picture , thanks for explanation , best regards
Andrej
Hi Andrej,
The symmetry line is a Line node which can be placed in several ways. I used the Place Line tool in the Place Geometry group on the Computational Design ribbon's Home tab. I place the end points in the locations shown in your screen capture.
Because the symmetry plane that I want needs to align with that symmetry line, I place a CoordinateSystem node using the technique ByParameterAlongCurve on that symmetry line, using 0.5 a T value (any value between 0 and 1 will do), and using the baseCS's ZDirection as UpVector, so that the resulting coordinate system's XZPlane is vertical to the design files X-Y plane.
Bottom line, this is just one of several possible ways to create a mirror plane in a location that can be easily controlled by moving the symmetry line's two end points. Any other set up that results in an appropriate mirror plane will do, too.
HTH,
Volker
PS: I am currently post-processing the March SIG recording. I expect it to be posted sometime next week.
thanks but now i stop either
how to mirror coordinateSystem2 to change coordinateSystem5 and points9,10 too, tricky
thanks
regards Andrej
Perhaps wait until recording and materials are posted to the GenerativeComponents SIG workshop learning path. Then take a look and post any additional questions.
Regards,
I needed to recall some basic properties and skills of GC and voila I did it plus easy slider to change ZTranslation
all is working perfect. see pic,
btw, I think after my last experience with learning space that it is or would be very usefull to update and better fully reorganized structure of working with LearnServer and better searching and orienting in LearnServer
all best regards
Good point about the LEARNserver content. SIG recordings are posted in chronological order. We try to keep SIGs interesting for a broad spectrum of skill levels; to achieve this, we intermingle basic and advanced topics with abandon. This makes it challenging to chart a meaningful course through the SIG contents.
Therefore, I have added a Wiki entry suggesting a path through our various contents that may make sense:
https://communities.bentley.com/products/products_generativecomponents/w/generative_components_community_wiki/41876/suggested-training-sequence.
My goal is to keep this updated as contents is added.
