Contour Troubles

[MHiggins]

I am having two different problems with digitized contour lines when they are in a layout. First, parts of certain lines that exist in the model space disappear. Also, the contour lines will not show up as dashed lines, instead they are solid lines. How can I fix either or both of these problems?

Just a wild guess here, but is your PSLTSCALE in your layout set to 1?

Yes it is

If you have an LTSCALE of anything but 1 and PSLTSCALE is set to 1, it may
actually be showing your contours as lines with really long dashes and
spaces.

Try either setting PSLTSCALE to 0, or change your LTSCALE to 1 whichever
suits you best.

I'm sorry, but that's terrible advice. Most of us plot from layouts at 1:1,
and in that case, PSLTSCALE _should_ be 1, and LTSCALE should be 1 (or
perhaps .75, I understand that's quite popular.)

MHiggins, you didn't tell us if the digitized lines are actually C3D
contours (which I doubt they are since you don't have a surface,) or simply
polylines. Have you checked your polylines for LTGEN? Pick all of the
plines, pull up the Properties dialog box, and look for Linetype Generation
and make sure it is enabled. That will take care of most of the dashes
appear as solids. LTGEN determines how dashes are calculated across a pline,
whether based on node-node distance, or simply on distance along the pline
itself. We've found that LTGEN is almost always best at ON, but there are
some cases where the nodes are VERY important, so you have to turn it off.

HTH!

It's really not so terrible. It's a matter of preference. I _always_ use
an LTSCALE of what my viewport scale is because then I can see my linetypes
in Model. PSLTSCALE then takes care of Paperspace. For those rare
instances when I have viewports at different scales, I'll use
PSLTSCALE/LTSCALE at 1.

Just a habit I kept from when LDT automatically set LTSCALE to the project
scale. I guess C3D doesn't do this.

How do you handle multiple vports at multiple scales with that setup? I will
agree that the LDT/LTSCALE issue was a bother, but we have a routine that
changes the LTSCALE when you change from a PS tab to MS, so I've not run
into that in some time. It slipped my mind to be honest.

Cheers!

Like I said, I'll use the PSLTSCALE/LTSCALE at 1 for those rare
instances I have viewports at differing scales in a drawing.

That routine sounds pretty nifty. Any chance you'd be willing to share
that one?

Darron,

Here is the one I wrote. It's in lisp and was done early in my customizing career so there are a lot of things I would change. Use TM to change from model space to paper space and versa vice. TMM will bring up the settings dialog box. If you have any questions about it, don't hesitate to ask here or e-mail me hailey at landmarkltd dot com.
