SpiralTool

Make a series of spiral copies, such as creating a spiral stair. Spiral Copy consists of two consecutive transformations: first, rotate the selection around the defined rotation axis, and then translate the copy along the same rotation axis (called Forward)< br />
Four steps:
1. Define the point at one end of the "axis", and select it to "rotate" around the axis< br />2. Define the "direction" of the rotation axis and select the point to translate the distance< br />3. "Start point" of the required rotation angle< br />4. The "end point" of the desired rotation< br />"3" and "4" do not have to be in the same plane as the first two points. The vertical distance from the (infinite) axis of rotation is used to determine these angles and can be interpreted according to the auxiliary graphics rendered during the operation< br />
Reasoning can be used for all points. Input in the value box:
1. The number of copies (excluding the original selection) is "4" by default. After activating the command, you can specify a number in the value box followed by "x", and press Enter to confirm the modification< br />2. When you select the second point, you can directly enter the translation distance. The active mouse cursor still determines the direction of the rotation axis (total translation distance=number of copies X selected advance distance. To set the total distance to the "selected" advance distance, press and hold the Alt (Command) key when clicking the second point, or append "/" when directly entering advance)< br />3. After selecting the start angle point, you can enter the rotation angle (in degrees)< br />4. Components and groups will update entity descriptions to display their copy numbers< br />5. If the plug-in has been used in the current model at least once, typing a number followed by "r" will only use the previously selected parameters, and repeat the selection operation for the number of copies specified in the text input. Entering "- r" will also use the previous number of copies. Currently, the number of copies per operation is limited to "200" to prevent accidental input of a large number of copies< br />6. After running this tool, the last replica of the initial selection will be selected, and the tool will remain active so that users can continue to spiral more replicas.
