During the acquisition of the measurement points the dimension chains are able to capture the points correctly even if the dimensions have been indicated in a different sequence or if the dimensions overlap.

The picture below illustrates the interconnections:

1. shows a dimensioning using the ’Continuing Dimension Chain’ option and the following sequence: First, click the distance C/F, then point D, and finally point A.
2. shows the result if the first dimensioning is like (1) and the next input is the dimensioning of the distance from the dotted line to point B. The ‘Combine Identical Dimensions from 3 on’ option in the detail style is active as well (since A/B, B/C and C/D were created!)
3. shows a dimension chain without the ‘Continuing Dimension Chain’ option. The following was dimensioned: the distance A/C and then D/E. A new measurement of the distance B/F would now divide the distance of 400 and create a second measurement from point E to F.
