Remember you might want to cut clearance if you are going to rapid prototype your cut thread parts. That completes the internal and external cut threads. Sweep the cut tool and subtract as was done with the external thread. Create a new Helix path for the internal threading tool.ġ8. Turn the Internal Threading Tool layer on. Add a 0.75mm Chamfer to both ends of the hole in the nut.ġ7. Repeat the same procedure on the other side.ġ6. Use the Intersection tool to derive the intersection between the two solids. Extrude the larger circle that is tangent to the hexagon with a taper of 45° (or 45°)ġ4. Extrude the hexagon to the center of the second circle as shown. Turn off all layers except the Nut Sketch and Nut Solid layers and make the Nutġ1. Subtract the Sweep and make sure the rod is on the Rod Solid layer and turn off the other layers.ġ0. If you are going to rapid prototype the part via an stl file you might want to make a copy of the thread cut shifted along the axis the desired clearance distance.ĩ. Start the Sweep tool and select the cutting tool sketch.
(Tip: If your z‐axis happens to be pointing in the wrong direction you can track the axis of the helix by pausing over the center of the start end and then tracking in desired direction of the axis.)ħ. Autocad 2007 tutorial pdf civil engineering If you don't find a book related to the engineering construction you're looking for, get it in your email These books and e-books are lessons for a draftsman to learn a drawing of CAD and engineering. And then track along the axis going a couple of turns beyond the end of the rod. RMB select turn Height and enter a height of 1.5 for the pitch of the thread.Ħ. Press enter to accept the same distance as the top radius.ĥ. Then select the Intersection of the corner of the cutting tool as the base radius. (Tip: By selecting a circle center point we automatically set the z‐axis perpendicular to the circle if DUCS is turned on.)Ĥ. Select the Helix tool and then select the Center snap point of the end of the rod.
Turn on the External Threading Tool and Helix Path layers, Make the Helix Path layer the active layer.
Turn off all layers except the Rod Sketch and Rod Solid layers and make the Rod Solid layer the active layer. Check the Machinery’s Handbook for complete information on thread forms.Ģ. Open the file named Tutorial 4 Threads.dwg. Precise 2D sketches of arcs, lines, polylines, and splines in any location as well as the 3Dġ. This tutorial assumes that the user is completely familiar with creating The new 3D modeling tools in AutoCADĢ007 allow you to model true helical paths that previously were not possible to model inĪutoCAD.
One of the most common questions that comes up when beginners are learningĪutoCAD 3D is how to create a cut thread.
