Hi tinigjeo,
The suggestions here are sound ones. It is always a good practice to draw your geometry at real scale 1:1.
So, if your model is not drawn this way, I suggest that you use Layer Property Manager to unlock, turn on, and thaw all your layers in your model. Then use SCALE and select ALL. You can apply your scale factor to get everything into real world dimensions.
Then you can use a layout in paperspace to create a viewport of your model. This allows you to zoom in or out to the appropriate scale.
If you need additional assistance or resources for any of these steps please update your post. If you want to attach your drawing, I can use it to make a video of the steps for you.
