Rotating an object

thespacegamer

I want to create a circle and rotate in 90' to make it verticle. I've played around with that rotate tool, it just rotates in along a point, but not actually rotating it along the red or green axis, which I need to do by 90' to get is to go the way I need it.

Is there a way to just pick an axis and rotate the object without using that tool?

Have you noticed the rotate tool changes color when at a particular axis? Draw a simple cube and hover over each face with the rotate tool selected. It will changed according to axis.

This is of course if your cube is drawn along this axis!

When the axis you want is over the face hold shift and you will lock that axis of rotation.

So double click your circle with the select tool(spacebar) the inference the axis you want with the rotate tool(q) and rotate your circle along it's axis.

Or you could just draw your circle on the axis needed in the first place

Orbiting so that you see the 'sky' and moving your Rotate cursor into free space in the sky will cause it to change to red or Green depending on the sky quadrant you are looking into. Looking at the ground it will be Blue. Lock it to the desired axis by holding down Shift.
The Rotate cursor will infer it orientation from free space or any face it's over. If that face is axial the it will turn Red/Green/Blue as appropriate - otherwise it's Black - us e Shift to lock the cursor and then click somewhere to start the rotation. To fix the rotation axis to a given 'line' drag the rotate cursor along an edge and stop somewhere part way along it and it will then lock to make that 'line' the rotation axis.

The above advice is all correct, but this may be easier. I assume you start with an empty model.

Drag out a Rectangle. (It will be, by default, in the RG plane.) PushPull it up into glorious 3D.
Triple-click your box, Right-click Group. (Otherwise your circle sticks to the box.)
Choose a face and draw your circle on that face. No rotations required.

Yet another way;

Draw your circle as you would normally
Select all (your circle), now select the Rotate tool
Click once but do not release the left mouse button but drag it horizontally until you find it aligned to where you want
NOW release the mouse, pick another point and start the rotate operation as you would otherwise.
I wish the circle and polygon tools worked the same way...
