requirements for making a valid 3D printable part. The basics are these:
1. Construct the curve forming the shape of the part (I use 6 points and an interpolated curve.)
2. Use this curve to make a Sweep1 surface
3. Extrude a small square along this same curve to make a make a square-shaped ridge and cap it. (I've tried triangles too.)
4. Make a circular Curve Array of 3 specifying the number of ribs you want. Be sure to use a rail curve that matches the sweep curve in 1.
5. Twist these ribs a specified # degrees, and then twist them the same number of degrees in the opposite direction.
6. Join 1 & 5 and you're done - almost. As I said, the top of the part will be flat, so I add a small circular cone to make it come to a nice point.
For 3D printing I had to give the basic surface thickness so I could control the amount of light transmitted through it, and also to eliminate naked edges, so Step 2 is actually more complicated than I indicated above. …

line for a slab (box/story).
The New Polyline Parametrs are:
1. Both new and old polyline should have the same 4 segments in its beginning and its end.
2. The New Polyline changes periodically in each axis independently.
3. I each axis they are 2 main options:
A. (in each axis) The coordinate is either equal to the "old" coordinate.
OR B. Differs form the "old" coordinate in a certain gap (specific for each coordinate) and always to the same direction (specific for each coordinate).
4. When it changes from "A" type to the "B" type and back appear the change need to be gradual therefor it need to be escalate during 4 segments.
I want to be able if it is possible to have the control of:
1. changing the paired of each axis.
2. control the discreet gap of each axis and direction.
3. define the minimum size of a segment.
Thanks…

one can see how the drainage paths generated from a series of fixed sources shift to find the slopes and valleys in the terrain.
For each source point, the algorithm:
1. finds the downward sloping direction
2. moves in that direction a designated distance
3. finds the closest point on the surface
4. if this new point is not higher or too close, then
5. it repeats from the new point.…
