Hello

After I have extruded a model from a 2d drawing it is still possible to change dimensions in the 2d drawing so that these changes will also change in the 3d model  
As an example I am constructing an inclined ramp and I want to change the angle. If I change the angle in the 2D drawing I only get a new contour which I have to extrude again is this wanted or is there a function to adjust the 3D model?

Hi @Papa_Schlumpf, Shapr3D is a direct modeling tool, meaning that the sketches are not connected to the bodies. You can directly edit the bodies using the modeling tools, eg. you can move and rotate faces to achieve the desired outcome.

Can you save new sketches from 3d modles ?  
After they have been tweeked from the original that created the 3d modle inbthe first place ?

Try out the Project tool.

Just add a plane to project the model on. Double click on the model and then click on the plane. The smart UI should show the Project tool option automatically.
