How can I import an STL file in a desired scale in RWIND Simulation?


When importing a model of the *.stl file type, you can specify the length unit used in the file.

During the first import, insufficient attention was paid to the STL file that has been scaled too large by a factor of 1000. The import works without any errors, but a look at the dimensions of the wind tunnel already shows that it is significantly larger than you would expect. Also, you can display the dimensions of the model by right-clicking Model - Edit - Info.

To import the file in the desired scale, it will help you to import this file in the length unit mm. The dimensions of the wind tunnel and the dimensions of the model are in line with expectations.
