Added Parts Different Colour than Older Ones

[MMH]

Thank you for all of your responses! They've been very helpful. I've currently managed to export the files from within MLCad so that parts from previous steps are greyed out; unfortunately, the quality of the images is sub par. Is there any way to export the images directly from MLCad (e.g. without using LPub) with a better rendering program?

Thanks again for your help!
