SolidMesh: Vectors Tutorial

Curve Application Examples

Create line

1. Pick two points and .

2. Pick any number of points and . NOTE: The curves generated are segments between each pair of points in the order picked.

3. Pick any number of points and a surface and .
NOTE: Although impossible to see the same points shown picked above are also picked in the second image below. The result looks identical to the pictures above but picking the surface caused the curves to be generated in the parametric space of the selected surface unlike the example above.

4. Pick a single point, a vector, and enter a in the field. Click .

Polyline curve

Pick at least two points and . NOTE: The curve generated is one complete curve from the first point picked to the last. Also, if a surface had been selected, a parametric curve attached to the surface selected would have been generated.

Create interpolated cubic curve

Select at least four points and . NOTE: One curve is generated from the first point selected to the last. Also, if a surface had been selected, a parametric curve attached to the surface selected would have been generated.

Normal line

Select a point and any number of curves and/or surfaces and .

Extract bounding parametric curves

1. Select a surface and .

2. Select any number of a surface's bounding curves and .

Create cubic curve

1. Select the start point and vector. Select the end point and vector. Set the to the desired values and .

2. Pick the start point and a curve containing that point. Pick the end point and a curve containing the end point. Set the to the desired values and .

Create quadratic curve

Pick a starting point and vector. Click .

Create circular arc

1. Select 3 points and .

2. Select one point. Set the desired values in , , and .

Create circle

Pick three points and .

Create arc segment

Pick the vertex (lower left point) of the arc segment. Pick the start point (lower right point). Pick the end point and .

Blend curves

Select two curves and .

Average curves

Select two curves and .

Snap

Select any number of curves and a single point and .

Approximate picked curve

First, select any curve as shown. Then change the display resolution to 11, shown in the third figure. Then pick the curve again, and select . Figure five shows the comparison of the original curve (set to a display resolution of 11) and the approximated curve. Since the original curve remains picked, change the display resolution back to 41, and compare the original and approximated curves. This is shown in figure six. The original curve is shown in red for comparison purposes.
