smeshenberg Posted December 20, 2016 Share Posted December 20, 2016 (edited) I can't get my camermatch to work. It's always way off no matter how I put my reference lines. I've tried multiple reference marks and lots of different placements of the reference lines and I can't get it anywhere close. Is it just me or is something strange going on?

smeshenberg Posted December 21, 2016 Author Share Posted December 21, 2016 (edited) Matt, I can't thank you enough for you personal assistance with this. You really helped me understand the importance of accuracy with the perspective lines. I also did not realize the importance of making sure that the reference object was in line with the perspective lines. For the forum - if anyone is listening - The problem was that I had the reference object way far away from the perspective lines, and not really on a point that the perspective lines were converging on. I also had my vertical perspective lines what I thought was just a couple pixels off. A couple pixels is a big deal. It really needs to be super accurate and you need to be sure that the vertical element in the photo that you're using is actually vertical. If you're using something like a pillar you're probably fine, but if you're using something like a home-made accent piece somebody installed, you're trusting your accuracy to that guy's spirit level. Thanks again Matt for your above-and-beyond level of support. Edited December 21, 2016 by smeshenberg Hit Enter too soon 1 Quote Link to comment
Vectorworks, Inc Employee Matt Panzer Posted December 21, 2016 Vectorworks, Inc Employee Share Posted December 21, 2016 You're very welcome! I'm happy to help! Just to clarify, the reference object (in the design layer) and the reference target (in the Camera Match object) should be placed somewhere on the vertical place containing the measured line (the control line given a dimension). This is assuming you're using a left or right control line as the measured line. If using the a vertical (blue) control line as a measured line, the reference should be placed somewhere along the axis of that control line. The purpose of this is to allow Camera Match to calculate the proper camera distance. If the reference is not placed correctly, it results in the wrong camera distance. Just to note: The camera distance can still be corrected using the tune view's "camera distance" control. So don't get TOO worried about this. As you mentioned, the accuracy of the control lines is very important. All three vanishing points directly effect one another in the calculations (in ways you may not expect). 2 Quote Link to comment
AlanW Posted December 22, 2016 Share Posted December 22, 2016 Matt, What an incredibly simple and clear walkthrough of part of the process. We need more like this and the best part was that you were thinking out loud which helps in dealing with problems we face when doing this. Thanks 1 Quote Link to comment

I can't believe it's not more widely available. I've been trawling through every bit of info on Camera Match I can find + unless I missed it I don't believe anything out there explains the relationship between the Reference Target + the measured line as well as you do here. And showing so clearly how dramatic an effect tiny tweaks to the control lines have on the preview object.

Technoflash Posted April 14, 2023 Share Posted April 14, 2023 Hi Matt Just trawling through your mini tutorial, very interesting, thankyou. My issue is that the Reference object and the Camera Match object don't line up. What's the point of putting those two points in if they don't align immediately and become the centre of rotation or scaling for the model? Also, can you use the horizontal reference lines instead of the vertical, I can't get a good vertical reference measurements for those lines.Cheers Mike Quote Link to comment

These points should align when you click on the "Set View to Match" button in the Objet Info palette. They also should stay aligned when using the "Fine Tune View" dialog (also invoked from the Object Info palette). Is this not what you're seeing?

You can select any of the control lines as the "Measured Line" by selecting it in the popup in the Object Info palette. Quote Link to comment

Hi @Matt Panzer Just watching this video as I have an issue with my Camera Match. Attached is a screenshot showing the model too high. Following your video, I think I need to relocate the Reference Point but I can not get access to it to edit it. On the Model I have placed it at the top of the wall, as I have placed it at the top of the wall in the image, as the bottom of the wall can not be seen. I have indicted the location of the reference point with a Blue Blob. So, two questions; Why are the reference points not aligning with each other, and, I can can not seem to gain access within the viewpoint the relocate the reference points and lines. They are all hidden by the model. Shown this is the second screenshot. Any help would be appreciated, as essentially the model is in the correct place, just way too high. Kind regards Mike Edited February 6 by Michael Siggers Added image showing location of reference point on model. Quote Link to comment
Michael Siggers Posted February 6 Share Posted February 6 Hi I seem to be having a problem with Camera Match. Despite the Reference Point being in the same place on the Model and Photo, (top of wall on the corner), for some reason Vectorworks thinks I want to build a house on top of a house, rather than at the same level. I can not figure out why this is happening. On the Model I have placed it at the top of the wall, as I have placed it at the top of the wall in the image, as the bottom of the wall can not be seen. I have indicted the location of the reference point with a Blue Blob. So, two questions; Why are the reference points not aligning with each other, and, I can can not seem to gain access within the viewpoint the relocate the reference points and lines.

Michael Siggers Posted February 6 Share Posted February 6 I've also notice that the Camera Match reference in mine does not show Green, Red and Blue. Could this be the issue? Below is form the Online Vectorworks help "The Camera Match reference provides Camera Match with the model’s orientation in 3D space. It is positioned on the model to define the planes where the vanishing lines lie. The three color-coded axes define the following vanishing points: Green: Left vanishing point Red: Right vanishing point Blue: Vertical vanishing point" Mike Quote Link to comment

That does sound odd unless you have "Black and White Only" selected in your view settings. I have not yet been able to download the file but I'll take a look at it when I can get it.

Vectorworks, Inc Employee Matt Panzer Posted February 7 Vectorworks, Inc Employee Share Posted February 7 Hi @Michael Siggers, Something seems off about that file that somehow triggers the shift in Camera Match's calculated view. While I have not yet found why it's happening, I have found one (less than ideal) way that seems to correct it. When I take your file in VW 2025, export it to a VW 2024 file and open the exported file back into VW 2025, the problem seems to go away! Hopefully the will help you get around the issue for now. In the meantime, I'd like to investigate this further when I have more time. ScreenFlow.mp4 1 Quote Link to comment

Mmmm, has not worked for me. Must be missing something. Exported as VW24, Closed file, Opened VW24 file, got the usual warning and it added vw2025 on the end. Still floating in the air.

Michael Siggers Posted February 7 Share Posted February 7 Apologies @Matt Panzer Opened the Viewport, selected set View and it moved correctly. That will do it for now, and would definitely be interested in what caused it. Mike Quote Link to comment

I submitted a bug with that file so we can take a closer look. In the meantime, if you notice anything that seems to trigger the issue, please let me know. Quote Link to comment
Michael Siggers Posted February 7 Share Posted February 7 So frustrating. Nearly there, but trying to fine tune it, and it seems to line up, but then moves again when I update the Viewport. Screenshots attached. Mike Quote Link to comment
