    Hi,

    I would like to know how I can change the North in my model without having to rotate it.

    Thank you

    Solar north for shadow study? Have a view called true north. Thats a site plan with true north as the orientation in the plan properties. Our template comes with one, but easy just to duplicate the project northplan and change that property for the duplicate. Then to manage tab and find the location icon. Use the rotate true north tool, and voila. Project north will stay the same in the other plan. All this can be found easily by pressing F1 for online help. Sometimes the online help is contextual for the tool you are using.
    Cheers

    Turn on your hidden objects by clicking the little light bulb at the bottom in 3D view. Click on the project base point symbol, unclip it and change the degrees for a new truth north. Another option

    Hi,
    thank you. I tried to do as you told me but the True North doesn't seem to change.

    Hi,
    thank you for your reply. I need to change the North for energy calculations. Do you think, in this case, is it enough to change True North or do I need to change Project North as well?

    Only True North needs changing, Project North relates to the project model itself as I understand it. True North needs setting up so that when a plan View is set to True North in its Properties (see Parameter Orientation in the Properties) it shows North as 'up' in that View and the system knows the orientation of the project for shadows, energy calculations etc.. Unless your project happens to accidentally be aligned to True North changing a plan View parameter from True North to Project North and back again should show a change in the orientation of the project within that plan View.

    Setting True North in any plan View tells the system where North is for the entire project.

    'Rotate True North' command can be found in Manage->Position->Rotate True North, but make sure the plan View is set to True North in the View properties before inputting any values for the amount of rotation.

    It is quite confusing I find and often I calculate the amount of rotation by using reference planes and the dimension tool first to find out how much rotation is needed to make North correct for the whole project. When entering the value for Rotate True North I sometimes get it wrong and Undo it as the result wasn't correct, then make it a negative value as working out whether it is a positive or negative rotation value to enter can be a head-scratcher.

    You can have several goes at Rotate True North - just so long as you end up with the plan View set to True North being aligned to true North.

    I hope that helps

    Thank you for your help ,

    I tried as you suggested and I used "Rotate True North" command to rotate the building until its real North was "up" in the current view.

    It is the View that is aligned to True North, not the building, but I assume that is what you meant
