Hi, I have the following 2 x command lines on Alias’s for quick rotation.RotateView LeftRotateView RightEach time you run these it turns the modelspace viewport or a layout detail viewport by the degrees set in the Rhino Options:FILE - PROPERTIES - RHINO OPTIONSThen look for the Rotate menu on the right hand side.Increment in divisions of a circle: 60which effectively makes a 6° turn every time you run the command.Change to 72 if you want 5° increments. Or change to 4 if you want to turn 90° each time.Note that this applies to modelspace Top view.

• Rhino Rotate Object

Rhino Rotate Object

Click Modify menu 3D Operations Rotate 3D. Select the object to rotate (1). Specify the start point and endpoint of the axis about which the objects are to be rotated (2 and 3). The positive axis direction is from the start point to the end point, and the rotation follows the right-hand rule. Specify the angle of rotation.

Layout Space is normally Top view but same here.Hope that helps Michael VS.

. Use Solid Difference to remove the pipes from the foot. As a result you should get a water tower with vertical grooves in the foot.However you might get an error Boolean difference failed.

In the command line. There are known limitations to boolean operations. Normals do not point the way you expected. Control points of objects are on the same place. Objects have surfaces on the same placeBasically there are two ways to solve problems with boolean operations.

The easy way and the hard way.The easy wayThe most easy way is to move an object a little to prevent objects sharing the same control point and/or surface. Continue from point 2 after the creation of the pipe. Use in the front view Transform Move to move the pipe a little bit downward like 0.01 or even less. Continue from point 3 and make the grooves in the foot of the water tower.The hard wayBoolean operations are actually a combination of several Rhino commands like Explode, Intersect, Trim and Join. Because of the complexity you need to organise your model. Again continue from point 2 after the creation of the pipe.
