By the end of the month, we will have a new tutorial uploaded to our Visualize MySolidWorks learning path specifically covering the Decals.
In the meantime, all you have to do is select the decal in the Viewport with the blue part selection tool:
...and then enable the Move widget:
This will expose handles on your decal and will allow you to place it on your part. Click/drag the yellow cube in the middle of your decal to place it on the correct part, and then use the arrows and green arch to fine tune the placement.
That was easy!
I have done all the Visualize learning path tutorials and they are EXCELLENT. I look forward to the next batch.
Great! Thanks for the kind words on the learning path tutorials. The next batch goes into even more detail, and also covers many of the advanced features only available in Visualize Professional.
