Topic: scaling in x and y without loosing z

[drizzt]

I have a drawing with contour polylines in LDD 2000. I need to scale the drawing without loosing the z value of the polylines. Can this be done? I tried the scale command with no luck. I also tried converting the polylines into contours with no luck.

Thank you in advance for your help

As a block or xref, sure.

i tried the block idea, I will try the xref next

no luck, am I doing something wrong?

This is an LT trick, I do not know if it will even apply for you, but here goes.

Make everything a block and make sure allow exploding is checked, and scale uniformly is not checked.

once made, select the block and open the properties box if it isn't already.  In the properties you will have scale x,scale y, and scale z.  Adjust them as needed, then explode as needed.  Please though, save this as a temp drawing first

Attach/overlay the xref, then use PORPERTIES to modify the X and Y scales.

why are you scaling the data at all?

  Probably to exaggerate the relief.

I am asking because there is probably a different solution for the user....

Well offer it up.

OK, IF the user has land as stated, then they might use MAP to assign proper Coordinate systems to the data (as this is most likely the 'source' of the scaling issue, or....they somehow got 'contours' from an arch drawing THAT do need to be scaled, although I think the Z would also be wrong in that instance, then the block method might be the most direct path.
All that being said, IF the user has data that is say METRIC and they need it in Imperial units, then a MAP query would directly affect the data for the change in units.

I would still like the user to forward the data, or provide a better explanation of the what, and where the data came from.

mike,

you are correct, I am scaling to adjust coordinate system and units difference to merge multiple drawings. I need to match a csv file of panel points from a surveyor in state plane central. when the company that used the aerials to do the topo map, the used state plane central. I need to move the drawing to state plane south (easy enough) but for some reason, the panel points from the surveyor that went to the site (whom I am sure is the correct one) and the company that used the aerials to create a survey map don't match. The topo map needs to be scaled 0.999875. I actually belief this is the difference between us survey foot and the international foot.

this  is a task best done with MAP,
be sure each drawing has proper CS assigned, (and the data is really in the right location)
then use MAP query into a new session set to the desired CS, when the query is executed the data will be adjusted by default, in MAP>>OPTIONS

Thanks,

I will give this a shot

[drizzt]

thanks for the advise, but I think xref without binding will work best for me, that way I will keep a record of the old (bad) coordinate system. I can then scale the xref inside the corrected dwg, and not touch the original drawing.

[mjfarrell]

the query process does not change the original data (drawing) unless one performs a SAVEBACK operation to the source file(s)

[drizzt]

That is correct, I wasn't thinking on that one!
