Now let's look at another model where the 1 inch cube model was saved to STL with measurement of 1.00 (instead of 2.54 like Inventor does it). The correct measurement is 100 times smaller than what is currently shown so we need to multiply it by 0.01: ext.calibrateByScale('in', 0.01)
That is still not correct, since we started off with the wrong measurement of 2.54m instead of 2.54cm. So we also need to calibrate the Measure tool. I can also change the unit which is shown from meters to inches: = "in" Note: if you want to play with these settings on Fusion Team, A360, BIM 360 Docs or some other Viewer instance, then you can do that from the Debug Console by referring to the Viewer instance as NOP_VIEWER - see Do simple Viewer API tests quickly You just need to get access to the Measure tool extension, and then can access various properties: var ext = viewer.getExtension("Autodesk.Measure") If you output to a linear file, you will need a linear-to-display LUT. If you output to a log file, you will need a log-to-display LUT.
But I'm unable to find where do you calibrate the tool It-s giving me measurements of 20 cm when in fact the wall is easily 1.20m. Hi forum people, I'm using the online TrueView webpage to get a few measurements of walls in a house.

So when looking at my 1 inch cube it will be saved with lengths of 2.54 (meaning 2.54 cm) and the Measure tool will show this:Īctually, I've already changed the precision from the default 1 to 2, so that it's clearer what the exact measurement is. When you calibrate your monitor in Lustre, the image that you view is an exact replica of that which is sent to the output buffer-with the monitor calibration Lookup Table (LUT) applied on top. True View measuring tool - how to calibrate. In case of saving to STL from Inventor, the internal length unit of Inventor will be used, which is cm. Then I used this to get the scale factor - var measureExtension NOPVIEWER.getExtension('Autodesk.Measure') var factor measureExtension. The program automatically attaches the resulting PMP file to the plotter configuration (PC3) file that you used to perform the calibration test.When the original file contains no information about the unit of measurement used (I find this in case of STL files) then the Measure tool in the Viewer defaults to meter / m. I manually calibrate the model using calibrate tool to meters by picking two known points in the model. When you finish the Calibrate Plotter wizard, a plotter model parameter (PMP) file is created to store the results of the calibration for the plotter. The program then scales the output based on the entered calibration values for the plotter to correct errors in its hardware scaling.
