Cannot exit out of the Shapes dialog once initiated. At this point, no other commands or dialogs in Prosteel will function.
Please follow the below steps to achieve this.
Prosteel doesn't support the right click menu for Microstation.
1. Launch the Prosteel application.
2. Go to the Backstage File > Settings > User > Preferences or type Preferences in the Search Ribbon and click on it to open.
3. Now, go to the Category Input.
4. Change the value for "Reset Pop-up Menu:" to "Press and Hold".
Now shapes can be inserted and the dialog can be properly closed out.
