seand Posted February 23, 2006 Share Posted February 23, 2006 to all 3d power guru's. How do I draw a spiral string for a staircase with rectangular section, the spiral comand works but orientation of the rectangle is all wrong, is this user definable? Quote Link to comment
mike m oz Posted February 23, 2006 Share Posted February 23, 2006 If the spiral is constant you can distort the profile vertically to compensate for this. If the spiral varies try extrude along path. In both cases you will probably have to use solid subtractions to get one or both ends terminating correctly. Quote Link to comment
Kaare Baekgaard Posted February 23, 2006 Share Posted February 23, 2006 Yes it is... Ungroup the spiral object. Convert it into a nurbs curve. Draw the rectangle and extrude along path with the nurbs curve as path. Edit group and select profile as component to edit. Rotate rectangle until it is right where you want it. But I am not sure this is what you are asking for so: Create helix spiral and adjust it to your needs. Draw rectangle. Extrude rectangle along helix spiral. Adjust as above. Or: Draw rectangle. Draw locuspoint. Sweep both. Enter - say - 7200 as sweep angle and - say - 5 inches as pich value. Adjust by double-clicking the object and move around with the elements relatively.
