Isometrics are not generated from a specific model.
Suppose that a new model was created by copy-paste geometry to a new empty model. Using this new model, Stress Isometric drawings are generated. However, the isometric has many extra lines in the drawings.
Why can the original model create a perfect Stress Isometric drawing file but the 2nd file cannot?
Answer: file name
In the example given, the problem was with the name of the model. ex. "Rurociąg pary bez rozdzielacza DN150 w Londynie.dat".
The problem only occurred on computers where the current system local setting was changed to "Polish locale". A Stress Isometric was successfully created on computers set to "English locale".
Path name may be too long (max = 256, including the path + model name + extension) or may contain non-ASCII characters in its name.
1. Create a new folder on the desktop or same folder as the model
a. Only use typical ASCII character in the filepath
b. New folder name should be short, ex. TEST
2. Copy model DAT file to this new folder
3. Change rename model to a short name (ex. TEST01)
4. Run analysis and try to create a stress iso
Enhancement 1110386 has been logged to extend the filename.
Reasons why stress Isometric was blank or does not create a drawing file?
