construction lines

Recommended Posts

(Weren't those called "X-lines" in Autocad back in the day?)

Don't forget that you have a couple options in the mode bar when you click the line command:

1) you can start drawing the line in "center mode", instead of "vertex mode".

2) under the line settings, you can jack up the "line scale factor" to some huge number, making a line get pretty long very quickly.

When you say "construction lines", I think of Guides, which I use all the time. I like Guides because I can unlock, edit and lock them again. Anything can be a Guide.

AutoCad had (or has) Rays, which start at one point, and go on to infinity. In earlier days, I would use a ray as a preliminary line, draw a crossing line and trim off the infinity length.

I've never worked with construction lines in AC so I don't know the advantages or finesses of these, I'm guessing they are similar to guide lines in Photoshop, but there are several ways to get similar help with this in VWs:

1. I use this extensively when drafting myself (couldn't live without it):

It's not the same but take a look at:

Cursor Cross-Hairs and

Constraints>Smart Points>Horizontal/Vertical extensions

2. I don't use it, but perhaps the grid in snap options can be useful to a degree.

3. I also use a separate DL in which I use the grid bubble tool for all relevant grid lines and in this I sometimes place guidelines that are assigned to my Guidelines Class. This way I have full control over all types of important and less important reference lines and directions I might need in a project and how they are show or not. (I usually lock these after creation so that no unintended mishaps occur during drafting)

Something like that, yes. How do you do that in Vectorworks?

these are created by a preference called Snap To Loci. Snap to Loci used to be on the Vectorworks Preferences, but it is not there any longer. You can still access it with a script. copy this into a new vectorscript:


Procedure SnapToLoci;


IF GetPref(5) = True THEN







it will turn on and off the snap to loci preference
