OBJ files
Read 1278 times
* November 13, 2018, 10:55:57 AM
I am experimenting with drone mapping (DroneDeploy). The 3D available to download is an OBJ file, which I've not used before, but understand is common with 3D printing etc.

I can view it in TC, albeit quite slowly due to around 240,000 facets (it views effortlessly on their web platform and Windows 10 3D viewer).

But what I'd like to know, is can I view the image (texture/material) on the surface object, as both of these other methods allow?

Attached is a screenshot of the files they've provided. I can upload them if necessary.

From what I've read, recent versions of TurboCAD can integrate OBJ Materials (*.obj.mtl) with OBJ Objects (*.obj).

You might get faster viewing inside TurboCAD by opening the file(s) and saving them as TCW (TurboCAD native format).

Thanks Jeff.

Any idea how? I'm on v2017, and the online help doesn't seem very helpful!

I just downloaded a free small obj model with mtl (from Free3D).   In 2017 the materials did not come into TC, in 2018 the materials were applied in both Lightworks (the default in Tc 2018), and the RedSDK Plug-in.  The model looks better with the TC2018 RedSDK plug-in. than the native GDI/lightworks mode.  (but obviously it is extra cost).

Whether it will work with your files I don't know, but at around 80Mb, you won't be able to post the files on the forum.  You could download the 2018 trial (preferably on a spare computer) and see what you think of the quality of the obj/mtl in TC.

Thanks Andy. Files zipped here in case you happen to have a minute! -  ;)

No problem (in 2018).   I opened in 2018, saved as 2017, E-packed the file so the materials will be correct,  Zipped it so I can upload it.

Download and unzip the Landscape file zip, open TC 2017 and navigate to the tcw file, when opened it should automatically find the correct materials.  BUT. note I used RedSDK as I don't have Lightworks in 2017.

Thanks Andy, much to my surprise that works!

I don't really understand how 2017 can display it properly, but only after it's first been opened in 2018? So do I definitely need 2018 in order to do this myself?

Was it just a matter of opening it and 'Save As', or was there more to do?

I just opened and used saved-as to save it as a tcw file. ## EDIT ## forgot to mention, I then used the e-pack function in v2017to ensure the materials were located correctly so they will open on someone else's computer.  ## END EDIT ##. Looking at the other thread, it looks like they were going to try and get mtl materials into 2017, but I guess they run out of time, and just implemented it in 2018 instead.

An alternative to 2018 would be to find a program that can open the ogj with mtl, and re-save as a suitable format,  the file opens ok in meshlab, but the file formats I tried exporting from MeshLab didn't work with materials,  I did use Carerra to open the obj, and export as 3DS, this opened ok with materials in 2017.  Sketchup apparently has a 3rd party plug-in which can open obj files, and TC2017 can open sketchup files with materials,  but I have not tried the Sketchup plug-in.

Maybe Murray will see this thread, as he knows more than myself about mesh objects

I opened the file in 2018 and saved it in 2017 format, but opening it in TC 2017 resulted in a very poor rendering in Lightworks.  The only way I could make it look good was to switch to RedSDK and remove most of the Lightworks lights (keeping only Ambient and Headlight).

I've attached what I saw in TC 2018's Lightworks render, but I'd be surprised if you saw the same thing opening this in 2017.  I also noticed that saving from TC 2018 as a TC 2017 file was 3 MB larger than opening that file in TC 2017 and saving it as a different TC 2017 file, so a lot of... something... either got tossed or incorrectly optimized.

Perhaps saving it from TC 2018 as an older DWG file, then opening that with TC 2017 will do a better job.

I'm a geometry guy, Andy.  I know zero about materials.

Thanks Jeff. To be honest the quality of the model's photography wasn't good anyway, as I hadn't correctly set up focus etc on the drone, it was my first attempt.

What you've come up with is pretty much like I've got. Think I'll have to upgrade to v2018.

Can someone point me to how this e-pack thing works?  I can get the point cloud to open in 2018, but I'd like to have the materials applied, so I can differentiate between different parts of the drawing (trees, soil, rocks, etc.) . I'm trying to bring up the DroneDeploy OBJ files I got from my Drone photos of a lot we own in the Sierras so I can design the drive and site for a future home, in TurboCAD Pro 2018

Just save your drawing, then go to File/ e-Pack, the menu will let you untick what you dont want to pack in the file, save to a folder or zip, the zip will be stored in the same folder like the actual drawing if you dont change to elsewhere, or send it by e-mail, never tested the e-mail option.

I thank you very much.  I'll give it a shot.
