Summary
Command to create elements along a curve out of AutoCAD elements. The number of elements to be generated or a distance between the elements can be defined.

The program creates a distribution line bound to the original AutoCAD geometry. This distribution line references the created elements.

The created elements can be changed independently of the source element. If the source element changes, this does not initially affect the other elements. Only when the distribution is redone (command Edit Objects Along Curve or changing the distribution line geometry) the elements in the path are re-adapted to the source element. Otherwise one can use command Update Objects Along Curve to reallocate the source element back to the distribution line.

The length of the distribution line is taken from the original AutoCAD Geometry. The elements are created along these distribution line. The distance of the first element to the distribution line is taken into account.

## For creation of the elemente, the following options are available for use:¶

Fixed Number of Steps

The first element is the source element. It is not counted. The last element is generated exactly according to the lenght of the distribution line.

Step Size

The first element is the source element. Thereafter, elements are created at the given distance to the length of the distribution line. If the distribution length is not exactly divisible with the given distance, a residual length remains.

## Example: Space Frame System¶

• Some structural lines are drawn to define the first frame
• In this case three AutoCAD lines mark the position of the distribution lines
• Choose command Create Objects along Curve
• Pick the first AutoCAD line at the base of the frame (see 1A)
• Modify the distance between the generated elements in the dialog (here 3.15 meter)
• Pick both colums (see 1B)
• Repeat this with the bracing elements (see 2A and 2B)
• Change the distance between the generated elements in the dialog (here 1.575 meter) and repeat the command with the rafter (see 3A and 3B)
• Finaly the purlin is defined
