Machines Simulator / Re: UDC - from OBJ - coordinat...

Last post by EasyPLC_Master - March 25, 2026, 07:56:30 AM

Currently, the ideal workflow is to export each part of the model to be animated independently, with the origin or pivot point in the desired area.

The model editing tool is used to decompose models that are already composed and for which you don't want to use the 3D editing software to modify them.

We are currently working on a new update that will allow you to modify the pivot point or origin of each imported model without needing to use the 3D design software.
We will announce it in the corresponding forum section when it is available.

Thanks for the feedback Emiliano.
We will correct the points indicated in the next versions.

So what is the workflow for importing devices or machines designed in Inventor or SolidWorks, for example, to avoid having to manually reposition the parts in relation to the parent objects inserted in Machines?
Is manual placement always required?

Machines Simulator uses a different coordinate system than Unity.
When you split a OBJ model using the tool included in the component Model 3D, the origin (or pivot point) of the splitetd model it is inherited from the original model and does not fit the extracted part.
Then you must to use other component (empty, static or other Model 3D) to parent it and use the parent as the origin of the splitted model.
Then you can operate with the parent at your convenience.

Machines Simulator / Machines Simulator VR

We are testing Machines Simulator VR and have encountered several issues:
-We cannot interact with the HMI interface (touchscreens).
-IMPORTANT: In the pop-up window that appears when pressing the left trigger button, it is not possible to select any controller from the drop-down list. Also in this menu, it is difficult to quickly interact and swap the values in I/O list.
-In the main room, when we access the settings tab and select "Free Mode," if we move to either side, the volume slider (in the settings menu) changes position at the same time.
-Aesthetics: When the trigger button on the controller is pressed, the hand performs an animation showing a pointing finger, but when the grip button is pressed, no animation is displayed.


I hope these comments will be helpful in improving the VR module.

Perfect. Already I sent to info@nirtec.com all the test model I tried it. Thanks.

Machines Simulator / Re: Write outputs in the PLC

Last post by emiliano - March 23, 2026, 05:14:08 PM

That has not sense!

In Machines Simulator the PLC Outputs are read entities (due are wrtitten by the PLC) and the PLC Inputs are write entities (due are readed ny the PLC).

It makes no sense and is counterproductive for Machines Simulator to write the PLC outputs in a PLC simulation.

The purpose for which I needed to write input and output —which I did in a Unity+PLC communication script— is to work with digital twins, where there is synchronization between the real system and the virtual twin.
The system could operate in two modes, using a single P1 program (which reads virtual inputs and writes virtual outputs) on the PLC:
- Simulation mode: the P1 program running on the PLC controls the virtual twin (the virtual twin's inputs—sensors and buttons—are inputs to the P1 program; the virtual outputs read from the PLC control the virtual twin's elements).
- synchronization mode: the same P1 program running on the PLC simultaneously controls both the virtual twin and the real system (in this mode, Unity had to read the physical inputs from the PLC and write them to the virtual inputs; and likewise, read the virtual outputs generated by P1, write them to the physical outputs, and act on the elements of the virtual twin).

Please can you send to info@nirtec.com your .maq file where you're using the WebService component?

Machines Simulator / WebService isn't working

Last post by Ismael17021 - March 23, 2026, 08:57:38 AM

Hello, I am trying to use the object 'WebService' and in edition mode, it runs perfectly. I insert the script code in the script machine for the 'WebService' and I make some tries and it works good while i am staying in editor mode.

Then, when I try to open the machine model in simulation, it does not open the model and it gets stuck on the loading bar whilst it trying to load the 'WebService'.

I am trying to open a machine model with the 'WebService' object without script code, just in case I have some fatal error in script code that it does not work in simulation. It  is still not working.

Lastly, I am trying to open a machine model with the 'WebService' object without script code and with no other objects in one model. It is still not working.

I am using the v4.5.2 and v4.5.3 Machine Simulator versions and I can not make it works.
