Hi Moustapha,

It is not possible to import polylines or surfaces into Pix4Dmapper.

However, there is the following workaround to export/import polylines vertices (MTPs) from one project to another. It requires afterward to draw again the polylines between the imported MTPs:

  1. Draw your polyline: for each vertice, an MTP will be created;
  2. Go to the GCP/MTP Manager: https://support.pix4d.com/hc/en-us/articles/202558329;
  3. In the GCP/MTP Table change the Type of your MTPs from Manual Tie Point to 3D GCP;
  4. Click on  Export GCPs  (your polyline vertices coordinates will in this way be saved along with your project’s GCPs coordinates in a .txt or .csv file);
  5. Open your other project and go to the GCP/MTP Manager, click on  Import GCPs  and browse to your file containing the vertices coordinates;
  6. Click  OK  and draw again the polylines fitting the imported vertices from the other project;

I hope this helps,

Hi Margaux,
thanks you for your answer.
It is a suitable solution if i have just some polylines to draw. unfortunately i have a lot of polylines with thousands of mtps in my project, so i can’t do it through this workaround, it will take me too long.
I hope this will be developped in nexts versions.

Regards
