Dashed lines on exported raster image

[Mike91]

Hi, I've exported a few 2d graphics from sketch up and saved them as .tiff
As long as I look at them from the preview on mac they are fine but when I place them on an illustrator or photoshop file all the lines become dashed and the quality goes down.
How can I solve this?
Here are two images, one from preview and one from illustrator

Before exporting click on options and tick "anti-alias". Export the image at the double size you need and then resize it in Photoshop.

What does your image look like when saved as final .png/,tif/other image (illustrator or PS final output?)
IOW...this may just be a PS/illustrator display issue?

For editing in Illustrator you will be better off exporting as EPS File (*.eps)
Since EPS is a vector format this will allow you to edit the graphics in Illustrator and then scale to any size without loosing image quality.
