Scan C-Edges (3-D FFS)

3-D FFS > From c-edges > Framew > Scan c-edge

You can divide composite edges evenly by scanning reference composite edges. This is relevant, for example, if you are working with two or three guidelines. If the first line has been divided, you can use this function to divide the other two guidelines correspondingly evenly, thus enabling the cross-section to be placed correctly.

1. First define the part name for the new composite edge, or assign the new composite edge to an existing composite edge part.
2. Up to 3 lines can be used as scan lines. Choose the number you want and identify the scan line(s).
3. Then choose the intersection points that you want to be determined: all intersection points or the next intersection point to the scan line.
4. Choose the division type, if required. In the case of a scan line, the division can either be made automatically or by entering the direction.
5. Identify the composite edge that you want to be newly divided.

Example:

The following figure contains the cross-section of a basin, which is to be placed on the two depicted, closed guidelines. The two 3-D guidelines and the 2-D cross-section have been created as composite edges with the specified dimensions.

(1) Guidelines, (2) Cross-section 

Case 1: Set without scanning

The cross-section is set on the two original guidelines. As the figure shows, the setting is uneven, which is due to the fact that the two guidelines are not evenly divided.

(1,2) Guidelines, (3) Fitting point 1st guideline, (4) Fitting point 2nd guideline

Case 2: Set with scanning

In the 2nd case, a straight, vertical auxiliary edge has been constructed and divided. The Scan c-edge function has then been applied to the first guideline . For this, the following steps were performed once the function was called:

• Enter the part name,
• Choose "1 line",
• Identify the auxiliary line,
• Choose "All intersection points",
• Choose "In direction of the 1st guideline",
• Identify the 1st guideline.

The same process flow was then carried out for the 2nd guideline. The original composite edges of the guidelines can then be deleted.

(1) Auxiliary line, (2) New guideline 1, (3) New guideline (2)

If the setting process is now executed using the two new guidelines, it is done evenly.
