<div dir="ltr">Dear
Guillaume,<div><br></div><div>I used to have the same issue. After creating STLs with SOLIDWORKS and importing them into Gate, I noticed that it is not positioned correctly within Gate. I solved this issue by importing the STL into Windows 3D Builder, where you can set the origin of the model to 0,0,0. After that, if you import the STL model in Gate, it will be positioned correctly.<div><br></div><div><br></div><div>Best regards,</div><div>Eslam</div><div><br clear="all"><div><div dir="rtl" class="gmail_signature" data-smartmail="gmail_signature"><div dir="rtl"><div style="text-align:left">____________</div><div style="text-align:left"><div><div><div>Eng.

<br>
I use the STL import quite a lot and have never had problems. What software are you using to make the STL files? <br>
If you would like, you can send me your STL files and I can try.<br>

Subject: [Gate-users] Origin of STL file not preserved<br>
<br>
Dear users,<br>
<br>
I would like to import the geometry of an ionization chamber from a CAD software to a STL file in order to define it in GATE. I have to mention that I need all the pieces separately to attribute a different material to each one of them.<br>
However, it seems that GATE does not remember the origine of the space where the chamber was first created, leading to all the pieces being mispositioned in GATE.<br>
Does anybody has an idea how to bypass this issue ? Is it really an issue or am I doing something wrong ?<br>
<br>
Thank you in advance for your replies,<br>
<br>
Best regards,<br>
<br>
Guillaume.<br>
