General Discussion / Deactivate license on my computer
« Last post by lemme.drone on June 24, 2023, 06:58:13 PM »
I need to deactivate a license on a computer as there is a conflict when trying to install the software.
No problem.  Thanks Vid.  And thanks for the great software.  3DSurvey is an amazing tool!
Hi Steve,

I am sorry to hear that, unfortunately the step 1 needs to be repeated in this case, because classification tool always starts by resetting (clearing) selection first.

Eric Evans at Surveyors Source has a good You Tube video ("Field to Finish With 3DSurvey") on how to pull off precise elevations from a point cloud in the 3DSurvey CAD tab. I've found the video really helpful.  In the video, Eric pulled off the edge of a concrete stairway and created a 3D polyline line with it.  He used the CAD feature that 3DSurvey added earlier this year.

I recently used that feature to pull off precise points for features partially hidden under vegetation by looking at the hillside at an angle to see the ground surface under the trees and snap to the point on the object I was after.  It's a useful tool.
I was doing a Classification process in 3DSurvey last night but was only part of the way through the Classification Step 1 process when a lightning storm moved in and I had to shut down the computer. I saved the project. When I open it now and select the Point Cloud tab, it still shows everything I had selected where I left off (shaded in red) but if I click on "Classification", it clears all my previously selected areas. Using the "Select" button only selects by polygon but doesn’t seem to get me back to the into classification process. Is there a way to get back to Classification Step 1 and continue where I left off without losing my "Classification Step 1" selecting work or do I need to start over?

Hi Sam, Simply go to CAD tab, and place points on the ridges and trees, like so:

I am creating cross sections for a development combining CAD imports and drone photogrammetry mesh using the orthorphoto function within 3dSurvey. When exporting the orthophoto as .jpg or .PDF is there a way to get height data eg ridge heights of buildings and heights of trees. If so how? If not, will the function to do so become available?
Bug Reports / Mesh from CAD data issue
« Last post by jakub.lechowski on April 25, 2023, 08:04:51 AM »

Got issue with generating mesh from CAD data, program doesnt want triangulate surface as it should, got some lines in file to show where i want breaklines but it doesnt work. Usually adding/deleting some lines/points was a soulution but in this case it didnt work. Im atttaching .dxf file and few screenshots, v2.15.2.

Regards, Piotr.
