Creating lines/shapes over existing map

SketchUp Pro

Hi,

I’ve imported a map from Google to scale. When I draw over it, I get this weird distortion - anyway around this? Thanks!

It’s called Z fighting, it happens when there are two different textures or colors on the same plane, in your case is the satellite image and the default white color.

I’d just take it into layout and trace over and then export as DWG and import to SU! In layout you can control whether fill is on or off!

so, it’s Z fighting, it happens when you have 2 faces at the same altitude, one in a group or component. they can’t merge.

you have several solutions, Richard named one.

  • another I can think of is if your image is still a photo, and not a face with a material on it. if it’s still an image, using the style toolbar, you can switch to a line only style. the faces are hidden, but the photo being a photo, it’ll stay.

  • if your satellite view is a face with a material on it (from the location tool in sketchup, it looks like it is), you could draw inside of it : First, I would unlock the ground, and duplicate it on the side. Then, I would either explode that copy, or enter it, and draw straight on the faces. it’ll cut the faces painted with the satellite view.
    why copy ? so your original is still where it needs to be, still untouched.
    it’s something I used to do with physical models, you print a second set and you use it to cut your cardboard right. (sacrificial plan)

You can also turn on xray mode and change the line colour in the style settings so you can see it when drawing over the image.
