Model and tracker not lining up with ThingMark

[bjackson1]

Hello,

I have the thingMark scaled to 1, and I printed the ThingMark at it's default scale (5cm).

When I start the experience, it anchors the model about 20 feet beyond where I am looking.  When I look directly at it it looks almost correct, but in an Escher sort of way, when I try to walk around it, the Anchor is about 20 feet past the ThingMark.

How do I adjust the HoloLens's perception of the ThingMark's size so that it knows how close it is to me?

Also, I tried to take a picture of it with "Hey Cortana, take a picture" so that I could show you what I'm talking about, but the picture does not capture the hologram produced by the ThingMark.

Thoughts?

You must have the printed ThingMark be exactly the same size as the size specified in the Experience. You have made it 1 meter in the Experience, and 5 cm in reality, so what you are seeing is exactly what I would expect.

That is exactly what was wrong.  My assumption was that the scale of 1 was equivalent to the default printer Ted size.  You should make a note somewhere about the difference.  It's not obvious that that is happening.

There is a line about this in the ThingMark section of the Getting Started document, but we will be sure to highlight this in the documentation before we ship with MVP.

I did see that when I was reading through, but I did not pick up on the fact that it uses meters for units.  I designed my model in mm so you can imagine what it looked like the first time I did it!

I would suggest making the units more obvious in Thingworx studio.  I don't think many people design in meters.  How hard is it to change the units in Thingworx Studio?  Many of the models I use are in inches, and I'd prefer to not have to scale them manually after importing them.
