Rotate drawing view

[NachitoMax]

Hi

I need to e able to click a base view and rotate it about its x,y,z instead of clockwise etc. example

Baseview is showing the FRONT view.
Click the view and it changes to TOP and updates (no dialogs)
Click again and it changes to back view
And so on. It always needs to rotate down by 90 degrees.

Can anyone help me on this please 🙂

Hi Nigel,

Is this what you need?

Hi

yes that works great 🙂 looking at the code, the UpVector is the only option? what if i wanted to go the other way or even rotate left or right? i couldnt see any other options aprt from UpVector

Thanks

Hi Nigel,

You can rotate any way you like, you just have to calculate the new Eye position and UpVector.

In this sepcific case it was enough to swap View direction and UpVector to achieve what we need.

If you wanted to e.g. rotate the model around the Y axis of the sheet you would only have to modify the Eye position, nothing else.

Btw my code was incorrect because the Target should stay the same - it's the Eye position that changes. Updated the blog post.

I made a more generic blog post about it:

Hi

In your updated code, which part would i change to make it rotate left, right, up or down?

Hi,

If you rotate around the sheet X then it goes either up or down depending on the angle you pass in. If you rotate around sheet Y then it goes left or right.
