The manual production in pipeline construction is often related to the fact that either the capacities for automation are lacking or the production is too individual for a simple automation solution. However, automated production would increase productivity and quality, especially in metal processing. The challenge in the manufacturing process of fitting tubes is the batch sizes of one. Nevertheless, a non-time-consuming programming solution must be found to integrate a robot-based solution economically into the production chain. Offline path planning based on CAD models would be a suitable solution. To ensure that the robot-welded seams comply with the standards, there has to be consistent quality in the seam preparations. For the final quality the direct integration of the CAD flow would be important. Due to transport and limited space, it is often impossible to use sensors to scan the piping. In case of lacking technical documentation, the pipes are still measured by hand, especially when replacing or modifying pipelines.The geometry survey is done in several steps, first a rough drawing is made on the vessel, this is then converted into a technical sketch and only later transferred to a CAD programme. There can be several days between these steps and different operators. A method will now be presented to combine these steps with the support of a tablet. For this purpose, software is used on the tablet to digitise the geometries and prepare them for further offline path planning.
