Hello,
I have been using the Java API extensively so far to construct models from scratcn and automate complex tasks. I have set up the code development/compilation environment quite some time ago, so I am not anymore familiar with the technicalities. The code I used always created a new model from scratch, and did some complex analysis.
I am wondering if it is possible to use Java code as a 'macro', i.e. execute a certain sequence of operations in an *existing* model, and if yes, how to do it.
For example if I run the code below when working on an existing model, I get the pop-up message 'Model1' or something similar, and then an empty model, i.e. the code has cleared what I had before.
What I would like is for example get the actual model and make some modifications to it (for example add some geometry which is easier to code in Java than in the GUI).
Thank you
Daniel
