PhotoMatch Strangeness

dario27

I use a space navigator with sketchup but when modelling something with photomatch the camera feels over sensitive, almost like the camera is far away from the model and zoomed in. Any ideas what happening here? something about the scale of the model?

Photomatch has also been doing some weird things too.
The blue axes flipped upside down, and no mater what I tried I couldn't unflip it.
I closed the window and started fresh and everything worked fine the second time.

Does photo match have some odd bugs that would cause this or am I just doing something wrong?

Could you post the SKP file so we can see it? We might have some hope of helping you with it then.

I didn't save the model, i'll use same photo again and try to recreate it the problem.

I recreated the file and attacked it to this post, its a very basic one cube model, but its does have the same camera strangness happening.

One horizontal axis is out of proportion with the other axis, creating a oblong. Is ther a way to adjust a single axis scale?

I think you've got an image that isn't suitable for PhotoMatch. Have you got another image of the same thing from a different angle? What is it anyway? It looks to me that it would be straightforward enough to draw without using Photo Match.

Its a prop from the movie Terminator 2.
I was photmatching it to see if the measuerments i have match up with the on screen prop.

I read that with photomatch its best to use a photo with the corner of the building in the centre of the photo, so this photo isn't a great image to work with.

Photomatch works fine when i try to use it for buildings, its nice to know it might not be me doing something wrong and i can blame it on an unsuitable photo

This is what i modelled with the measuerments i found.

That looks good.

You're right about the image not being very good for photomatching. Problem is, you don't know what's happened ro the image that might have changed its proportions and that can make it impossible to get lines to run off to vanishing points correctly.

The prop was rigged to explode just after this shot was taken, it looked like it was just pushed together for a quick shot, and they probably used a wide angle lense...I'll stick to practicing on houses
