Allplan users now can build your own Allplan pythonparts library FROM parametric 3d modeling objects TO rebar detailing, section&labeling  without coding!

Create different types of 3D parametric objects: the tool has the ability to draw, design, model structures and modify the parametric objects depending on your own needs. It is the solution architects & engineers have been looking for in Allplan.​
If it is what are you looking for, check out the PythonParts Generator at

The individual parameters are used by referring to the corresponding attributes when creating the PythonPart. Please watch our Allplan python api tutorial on youtube here > 

Yes, PythonParts can be shared with other users without any problems. Just make sure you allow sharing file. If you build pythonparts with ALLTO Pythonparts generator, you can share .json file to Allplan community! We’re appreciated to build a strong community. 


If you don’t want to perform a full installation, you can replace the existing folder:


with the correct one by performing following steps:

1. quit Allplan 2023-1-2
2. open the ETC path (described below) and rename the existing PythonPartsFramework directory to PythonPartsFramework_OLD
3. use the following link to download the folder from our cloud
4. paste this folder into the ETC directory
5. start Allplan and test the execution of PythonParts. If the restrictions still exist, you have to go to the installation setup.

You can reach the ETC directory via the Allmenu as follows:

Service > File Explorer > General Program Data
After that you still have to change to the ETC directory and you will find the mentioned folder there.
