...please can you explain how you made the last step??
Mohammed,
Draw new diagonal line entities from the bottom corner of each step, to the next bottom corner. When done, you can select the new lines, and copy them downward by your desired amount. This will provide the bottom curved line, from the first floor to the second.
Note that I used groups. If you employ the above description while 'inside' the edit of the group, you have to use the copy feature of the move tool, then delete the original curve.
If, however, you keep the group closed, and draw your new diagonals on the 'outside' of the group, the lines won't 'stick' to the group geometry (but inferencing still works.) You can then move the new curved line downwards, without distorting (dragging) the geometry within the group. Once you have the diagonal curve in the new position, select the complete curve and use <ctrl-x> to delete it. This will delete and copy the entities onto the clipboard.
Immediately open the group for editing, and use "Paste-in-place" (Edit menu) to insert the 'deleted' curve into the group's geometry. The rest is cleanup and hand-stitching the underside. (You can use the 'Skin' plugin instead of hand-stitching.)
EDIT: See several posts down, for clarification regarding the rounded steps having two lines defining the outer edge. To draw the diagonals, this middle point has to be included, as well. xrok1 describes one method. [Sun Feb 15, 2009 5:20 pm]
