Align Images after marking all the GCPs?

Hello,

I am currently having a UAV project and I have to create an orthophoto and a DSM. I have around 10 GCPs. It took me a long time until I mark all the points on almost all possible images. But I would like to ask whether I have to click Align Images every time I mark a point or like in my case - marking all GCPs and then hitting align images? After using the Ortho Projection the results were terrible.
Moreover, I am confused about how to create a model.
I would be grateful if you write back a brief workflow on the topic how to create an orthophoto and a DSM.

Thank you in advance!

It is enough to click the align button after making all the changes that you wish to make.
There is a topic about Ortho-projections in the application Help. The updated and extended version is ready to be released in the next software update.

Hello,
I checked the ortho projection info in the Help. I think I am doing a mistake before that. Will try againa and get back to you later.

Thanks!

You can click the align button just after making all the changes.
