The Tangent Arc Tool in the ToolShed plugin has just been updated with a simple, but important improvement. Now when you begin drawing an arc, it can begin at any angle you want. Just click, and a guide line will be drawn from the clicked point to the current cursor location (press Shift to constrain to an increment of 45°). Once you press your mouse or stylus and begin to drag, the arc’s start angle will be locked in and your cursor location will determine the arc’s endpoint.
ToolShed 16.2.2 also adds stability improvements and is recommended for all users.
If you haven’t tried ToolShed, you can download it here and enjoy 1,000 free uses spread out over as much time as you need.
