How to edit the length of witness lines on-screen? {solved}

Anonymous — Tue, 30 May 2023 13:15:19 GMT

Page 401 of the AC12 reference manual states: "You can edit the length of custom and dynamic witness lines on screen for one or both witness lines of a dimension unit, or for all the witness lines in the chain: select the witness line(s) you want to edit, and drag."

In the example attached, I want to pull the witness line back from overlapping the wall capping.

I have been unable to do this onscreen with the cursor - only by numerical editing the Settings.

Am I missing something?

Select only the node you have highlighted in your screenshot and then move your cursor along the projection of the witness line to where you want it to end. You are effectively drawing this line with your cursor.

HTH

Thanks Erika - for the suggestion - but it doesn't work . I tried in both the plan and 3D document windows, to no avail.

I can dynamically edit all the witness lines of the unit/chain together - just not individual witness lines.

Attached the witness line settings, in case you can see any hint there as to why it's not working.

1. Activate the dimension tool
2. If you want to adjust all the witness lines of a dimension string, select the entire dimension string, place your cursor on one of the nodes when you get a check-makr, click move the cursor down as far as you want.

3. If you want to adjust only ONE witness line length select ONLY the node where the witness line originates, NOT the entire dimension string, and then move your cursor to define the length of a witness line.

Your profile says AC12. Is that what you are really using or is it AC13?

Well thanks Erika, and StressCo, I finally did it... although for anyone else having the same problem, there is also another missing piece to add, before it works....

Yep, that's exactly what I tried. But no go.

You're first suggestion wasn't in the manual : Activate the Dimension Tool.

But doing that, however, then clicking a witness line node just started creating a new dimension. So I chose the arrow tool, to "select" the node, then dragged. Nope - no go.

Then it occurred to me to Shift-Select the node, WHILE the Dimension Tool was active (So don't change to the Arrow/Selection tool before clicking the node).

Voila, problem solved!

PS. Erika: yes, my profile reflects my current setup.

Generally operations are more reliable and predictable if you have the tool selected of the element you are editing, but it is not always necessary.

To edit a dimension's witness line select the dimension, then click and drag on the dimension line (the one on which the number sits) and the witness line length will stretch IF you have used the Custom Height or Dynamic Height (right hand button) option in the dimensions' witness line setting.
