Sectional views from 3d scan

[Julie]

Hello,

I'm new to Agisot metahsape and I need to get sectional views similar to these from the 3d scan

Would you have any ideas on how to do this ?

The question is how to extract the cutting profile from Metashape and then process it in Photoshop if necessary.

Thank you

You need to use the Measure Profile feature. (see pic.1)

1) select the "Measure Profile" command.
2) Click the first point and then click again a second point along the line you need to cut.
3) Right click to finish the command.

In the window that opens you see the profile of the cut you assigned.  From there there is a save command that lets you save the profile in different formats such as .shp, .dxf, .jpg, .png etc. (see pic.2)

you can make some adjustments with the sliders to the depth range of the cut, an offset of the cut and the display of the point (solid, color, classification etc)

In order to use this feature you need to have the project referenced. This can be done with georeferencing, or with Control Points, or with scale bars.

Thank you !

The problem is that the 3D model from which I want to extract the cutting plan is an imported .stl file that I made with a 3D scanner.

There are no photographs with reference points or spatial coordinates

How can I do ?

In this particular case, it doesn't matter if the scale is right, I just need a visual rendering of the section plan.

Hi, Julie!

May be for a visual purpose you can cut a thin strip and capture it from the side.

You will need to switch to orthographic view mode (from menu Model -> View Mode), select a strip and cut it, then rotate a view to see it from the side

To capture a view you can hide everything (from menu Model -> Show/Hide Items -> Hide All), then right click on the model view and use Capture View from the menu. You can save it in png format with transparent background for further processing in Photoshop.

It won't be precise.
