以下是软件自带帮组文档中关于旋转轴的解释,希望以上的回答对你有帮助。 3.3. Rotation Axis You can define the rotation axis of a model here. The 3D view shows the current start and end points of the direction vector. When Pick on Nodes is checked, you can pick three points that form a plane, perpendicular to the direction vector of the new rotation axis. For this to happen, the camera symbol in the lower right toolbar must be inactive and the picking tool must be active. Start and end point of the axis are determined automatically. When Pick on Nodes is unchecked, you can enter the start and end points manually. By clicking on Adjust length the length of the axis is determined automatically, such that it sticks out of the model on both sides a little bit (about 10% of the model size). The upper left button reverses the rotation direction, the right button deletes the axis. Defining a rotation axis will not produce a cloned model but will set the axis for the active model itself.
我在使用中还没有遇到这样的问题,不过有这样的情况,CAD保存为DFX或者DWG时如果选择的版本过高就导入不成功,你试试把版本降低到2007版或者之前的试试。
刚才特意看了一下,不能设置为恒定的线速度,软件中只能是恒定的角速度。不过可以把线速度转换为角速度了输入进去
