Polylines drawn in image not snapping to surface?
« on: January 24, 2018, 10:51:47 PM »
I am running into a issue that I did not have with 1.3.  1.4 the polygon that is drawn in picture view is not snapping to the model.

Attached is a picture

And becasue of this the polylines do not match in every picture.

Any feedback on this.

The only way to make sure the poly lines are on the surface is to draw is in the 3d view.

Hello aaronfhd,

Just to be sure, are you drawing shapes in Photo view or in Ortho view mode?

Also it is possible that there are some abrupt elevation changes that are smoothened on the mesh?

In principle, you can enable Attach markers to shape vertices option in the Preferences - it will allow to adjust the projections of the shape vertices individually on each photo (you can do that on couple of images), like for regular markers.

I am doing this in PhotoView. In ortho it snaps to the elevation.. As I said before I did not have this issue in previous 1.3

I would draw the poly in photo it would snap properly. Now it does not

Hello aaronfhd,

Are orthomosaic, model and shapes in the same projection? Can you provide the past page of the report with the parameters used and project details?

Not sure what you are asking here but everything lines up in terms of markers on the images and ortho.

When I draw the polygon on a image I noticed they are not aligned on all the images like they where in 1.3.

If i draw it in the model/3d view it snaps to the model.

I don't know how else I can explain it.
