Height of entities in same layer

Max Oulton

Hi.
I'm the new boy on the block and have come across my first challenge. .

I'm attempting to create a 3d map of my University campus using SketchUp Pro and have imported a dxf from our building draftsperson. All the layers have come across fine but certain errors have come across too. The worst one is painted lines in car parking areas.

Some of these appear to be about 100 meters lower when viewed obliquely (the car park is flat!) and I need to get them all to appear at the same higher level — I can select the wayward ones but am struggling to find height attribute data to edit so I can raise them to the correct height . . . . .

Any clues out there??

Cheers & Thanks in anticipation
Max

Hi Max,

Simply move them to the correct height. Select them, press the up or down arrow button on our keyboard (to lock the move on the blue axis) and start moving. Now you can snap to any geometry (like the edge of the car park) to fix those lines.

Maybe there could/should be some other solution but without seeing the model, I cannot think of anything.

Sounds like he modeled the surface in 3d in CAD but drew/imported the carpark layout flat in 2d at z=0.
So moving them up will mess up if they are all flat and the surface is 3d.
A solution to this would be to group all of these carpark lines and then move the group vertically [as Gaieus explained]... but so that they end up well ABOVE the surface... then use the Sandbox tool's Drape function to make a set of lines drawn over the 3d surface - the 'flat' grouped set can then be erased, or put onto its own 'off' layer...

Thanks Guys - worked a treat. (original file created in AutoCAD with over 250 layers - there is a lot of extraneous data "floating" around which is slowly being deleted to get the file down to a manageable size).
Cheers and Thanks
