giri Jun 20, 2017 10:50 AM (in response to pyalu)Not sure I understand your usecase, but the coordinates are relative with the ThingMark location. Usually you can notice that the ThingMarks are always at (0,0,0) coordinate system. Moving the ThingMark will move the coordinate system in Experience View (i.e., only in ThingWorx View app).

Re: how can i find the origin point of the coordinate system of my 3D model?
pyalu Jun 21, 2017 1:46 AM (in response to giri)yes giri, u r right. But if i rotate or zoom the model in View app with "slide widget", the model will rotate with an unknown coordinate system. I can't find the (0,0,0) point. even i set x=0,y=0,z=0 in edit page in Studio. then in View, the model will also be rotated or zoomed abnormally. how can i change the unknown spin center to the one i wanted. thanks a lot.

tmccombie Jun 20, 2017 11:56 AM (in response to pyalu)Can you please share your expected behavior when rotating around the X axis?
I get the behavior you described as well. It is because we are rotating 90° with the X axis being the "spin center". If you notice in your screenshots, the X axis is the red line with an arrow and when you rotate your model 90°, the model rotates around this line. The transform tool is color coded to represent each axis. You'll notice that there is a red arrow and a matching red arc that represents the X axis. By dragging the model using the red arrow, we can move the model along the X axis while moving the model using the red arc, the model will rotate around the x axis.

pyalu Jun 21, 2017 1:33 AM (in response to tmccombie)hi Tara , thanks for your shearing. I understand your description. in twx studio edit page , we can rotate and translate by drag the 3 colored arrows and arcs to make the model change as we expected.
but in TWX View app, If i want to rotate or zoom out the model, firstly i have to set up an “slide button” in 2D（pic1） and binding the widget ‘s value to the model in twx studio.
At last, in View app ,when i change the slide button value to rotate or zoom the model, the model will rotate around the “unknown” coordinate system instead of the one showed in edit page of TWX studio. As u said, the model is rotating with the "spin center". so where is the "spin center" exactly? how can find the pvz model's spin center? this problem confuse me for a very long time.
thanks again for your help.
