Named View  1-20  21-27

I know I have asked Michael if he could add Named Views to the list of requests for MoI. With Moi's ability to do a nice job of exporting to Illustrator it has become an excellent tool for the technical illustrator. But it is vital to be able to go back to saved views in MoI when additional or updated output is required.

One day while checking out the forum I thought I saw a thread about a new script for setting a named view. Am I mistaken, or does such a script exist?

We have been discussing AI output from MoI in the Technical Illustrator's forum. http://technicalillustrators.org/forum/viewtopic.php?f=1&t=211

That might be the Camera switcher extension for CustomUI..

Hi Don, thanks very much for spreading the word about the new Illustrator / PDF drawing output!

That's probably one of the most interesting new features in MoI v3 since it opens up a new avenue of data flow for making illustrations. Combined with MoI's low cost and general focus on trying to be easy to use it should help MoI be a lot more useful as a companion tool for 2D illustrators.

Also it has some unique things in the export - you can get a hybrid mix of both shaded rendered background and also vectors on top of that, and also as mentioned in that other thread it's very typical for CAD program PDF export to only export a dense set of little line segments as the vectors rather than actually exporting smooth curves which MoI's new exporter will do. Having smooth curves helps keep the output to be more useful for various types of additional editing.

re: Named views - unfortunately there isn't really any proper saved named view mechanism available right now, there is the script that's mentioned above but I don't think those views will persist with an individual model file between sessions so it's probably not quite there. I would like to add a proper named view mechanism in the future.

- Michael

Hi Don, one thing I should mention is that although there isn't a "named view" mechanism, the current active view for all viewports is saved and restored when writing to 3DM format.

So if you want to be able to return to a particular view later on, one basic way to do that currently is to save out a copy of your file, your view will be restored when you do a File > Open of that same 3DM file later on.

This is pretty low-tech but it works. Save embedded image(s) with the 3DM file.

I must be slipping, I've had Moi for some time now and its been a life saver over and over again. Its obviously fantastic as a stand alone 3d program, but I also use it in conjunction with Solidedge when I need to do some complex surfacing. But I have completely missed the fact that I can use it for technical illustrations. I will be making use of this. The program just keeps giving. Thanks Michael.


The image is of a small agricultural machine. Built in Solidedge, full assembly model exported as a 5MB STEP file which opened in MOI quite quickly. Saved it as a AI file but for some reason Inkscape would not open it, so I saved it as a PDF and then opened it in PS. Fantastic.

Danperk, how are getting the camera and target information? My View Angles box does not have that.
Thank you,
Ron

Ooops, broke it. I tried with a 156MB STEP file with this result (see attached image). I think I've discussed with you Michael before about very large assembly models. MOI had no problem opening the file but wont save it as a PDF. My PC has 32GB of RAM so I don't believe that's the issue. Any idea as to assembly limit would help me.

Thanks

Paul

Looks great!

MoI saves to the older AI version 8 file format, while I think Inkscape's AI loader can only load AI version 9 and higher AI files which are actually the same as PDF files. For going into Inkscape try using PDF format export out from MoI rather than AI format.


> I tried with a 156MB STEP file with this result (see attached image). I think I've discussed with you
> Michael before about very large assembly models.

MoI does not currently have an instancing system, so if the STEP file has many repeated elements in it as instances, those will expand to independent copies of objects and tend to consume a lot of memory.


> MOI had no problem opening the file but wont save it as a PDF.

You're likely running out of memory during the PDF file generation, which requires a fair chunk of memory in order to do its own processing.



> My PC has 32GB of RAM so I don't believe that's the issue. Any idea as to assembly limit would help me.

MoI is currently a 32-bit program and so it is only able to address a maximum of 4GB of ram.

For heavier models it can help a lot to adjust a display setting to make a rougher display mesh. By default MoI makes a quite dense display mesh which makes things look nice on screen but can consume a lot of memory if there are a very large number of surfaces in the model like it looks like you have there. To make a coarser display mesh go to Options > View > Meshing parameters and set "Mesh angle" to 30 degrees and uncheck "Add detail to inflections". This will result in a coarser display mesh used for the shaded surface display which will make things look rather more jaggedy on screen but it will reduce the memory consumption load by quite a bit, maybe enough for you to get your PDF export done.

In the future I'm going to look into making MoI a 64-bit program so it can make better use of all your system RAM instead of only 4GB of it. There will be a lot of work involved in doing that though.

You can retrieve them through some script set up on a shortcut key, check out here for more info:

Yes I'm using the scripts Michael linked to, then paste the coordinates in Photoshop and imbed in 3DM.

Michael, it would be great to have the ability to add a text file to 3DM files if the they support it.

If the second script for setting camera point could open an input window for x,y,z that would be very handy too!

Thank you, gents! That may come in handy; and I missed it the first time around.

Hi danperk,

How about this - I've attached here a customized version of the Options > View > "3D view angles" dialog that now has controls on the bottom of it that allow you to both get and also set the camera and target points.

Put this new version in place of the regular file which is inside the \ui subfolder. Should work in either MoI v2 or v3.

On Windows the ui subfolder will be inside the install folder like this: C:\Program Files (x86)\MoI 3.0\ui , on the Mac right-click the .app icon and on the menu that pops up click "Show package contents" and inside there go to drive_c/moi/ui .

Thanks for supplying this Michael. This will work terrific. We can keep the data in a text file for now to copy and paste when required. Perhaps as you move forward with development you can incorporate this function to create and store the named view(s) in the drawing.

Another nice thing about this added camera function is I can now export my TurboCAD files to MoI if needed and set up the same view in MoI since all that camera data is easily found in TurboCAD.

Hi Michael,

Thanks for all your help. I tried the method you suggested and it didn't work for me. It is a large file and I gave it a thorough inspection. My STEP file is 156mb and 110 individual parts (actually, with all the fixings its more), so its understandable that your not going to get too much done in less than 4gb of RAM. So I broke the model down to 10 3DM files and I added a line all around the view so it would crop them at the same size on export, and saved each as a PDF. It worked out that the tyres are very memory intensive and to my surprise, some of the pipe work had to be left off as they took up too much memory. That and the front ladder. Compped the 10 PDF's in Photoshop (only 300dpi) and I have what I need. It takes a bit of work but now I have a process to do it, I can cost that in to any work I do. I look forward to a 64bit version but I know you have other things to think about.

Thanks again for your help Michael


Paul

Hi Paul, it's a really great looking result!

I'm going to be doing some exploration work on a 64-bit version for v4. There will be a lot of work involved in doing it and so I'm not entirely sure yet if I'll be able to do it or not but I will be investigating it.

Seems all the memory is consuming by the wheels ?
As soon as an instance system will be avaible some problems will be resolved ?

Yes, it will probably help out a lot for cases like this with complex repeated pieces.
