ArtCAM Lessons - Import-Export

ArtCAM (PRO 2018) is one of the best professional programs for creating models for CNC milling machines. Import-export in ArtCAM allows you to open up, edit and salvage files in unlike formats. Despite the apparent complexity of the programme, it is easy to acquire and with a picayune do allows even beginners to prepare models for the automobile.

ArtCAM also uses its own file format, has a built-in library (ordinarily downloaded separately as an update parcel) of models and vectors. All models created directly in the program tin can be saved in this library, which volition and then allow them to be used in other projects, too equally edited (resized in XYZ, deformed in XY, copied, duplicated).

Everything is based on my own experience, more than than 400 hours of work in the programme allowed me to understand quite well the intricacies of vectors and create new models​.

The well-nigh electric current versions of the program are ArtCAM 2008 and ArtCAM 2018, the transitional versions of 2010 and 2012 somehow did not take root among DIYers and professional person users (I judge by the amount of content on the Internet, although I could be wrong).

Basics — file formats *. rlf and *. fine art in ArtCAM 2018

It is worth knowing that ArtCAM 2018 saves the model in an ArtCAM relief file (*.rlf extension), while ArtCAM 2008 (in versions 2008-2013) saves the model in *.rlf relief format. art. An earlier version of the program uses a hardware security key, so you won't be able to open up *. art in ArtCAM 2018. You should take this into account when saving models and when moving to a new version of the plan.

How to open old *. art (2008) in the new program (2018)

When working in the programme for a long time, a large library of its files in the program may accumulate. If y'all decide to move from the old programme to the new one, you lot need to convert the library to the new format. In that location are two options hither:

1. Если библиотека небольшая, то можно перевести файлы в ручном режиме через сохранение в STL формате (как создавать STL файлы расскажу по тексту ниже).
2. Если библиотека разрослась до неприличных размеров, сохранение руками будет неэффективно и долго. Этот вариант тоже не простой, но позволит другим способом и пакетно пересохранить файлы библиотеки в новом расширении. Необходимо воспользоваться функциями более поздних версий программ.
   1. Here we have two options:
   2. The get-go option is to open the file library (2008 programs) in the newer 2013 and 2015 R2 programs. SP3 - open up the model and save information technology once again. And then files *. fine art are converted to *. rlf. Only unfortunately, this also needs to be done by manus.
   3. The second selection is automated. In the ArtCAM 2015 R2 program, an additional add together-in "Toolbox" was created. You lot need to use the Toolbox function in it:
      1. Shut all running ArtCAM sessions.
      2. Download the fastened File Convertor add together-on installer.
      3. Right click the ArtCAM 2015 R2 File Conversion Tool file. exe and select Run equally administrator.
      4. Sign in to the Setup Wizard normally.
      5. Launch ArtCAM 2015 R2.
      6. Click the Tools tab, then click the File Converter icon.
      7. Click Scan and browse to the folder containing the ArtCAM model files (*.art) y'all want to convert. Select this binder.
      8. Click the Catechumen Files push.
      9. A bulletin volition appear stating that the files were non backed up. Create it if necessary (you never know...).
      10. Click Yep to convert the files. When the file conversion procedure is complete, a success bulletin box is displayed.

Of course, you will need to install boosted programs, simply that's some other thing.

(I tried to work in 2008, 2010, 2015 programs, but these compatibility problems, every bit well every bit new technologies, prompted me to master the new ArtCAM 2018 program, so work in this program will be considered further).

Import-export of STL model in ArtCAM 2018

The most relevant file format for creating models in ArtCAM is STL. The program too understands and opens OBJ files. Now let's look at import and export, likewise every bit creating STL files and saving them.

(Importing and exporting in OBJ format is the aforementioned).

At a minimum, you lot demand to create a new model (empty) in the program.

When starting the program, nosotros are greeted by a window offering to create a new model.

We write the dimensions of the model, select the resolution of the model. Here it is worth stopping in more detail. That is, when creating a model of 20x30 mm, or a model of 1000x1000 the maximum resolution volition always exist no more than 4000x4000 pixels - this is a limitation of the program (in a separate lesson I will tell y'all how this limitation tin be bypassed and raised resolution up to 10000x10000 or more).

Therefore, if you are working with a small-scale model, you need to create initially within similar limits, without a large margin. That is, if the future model (imported or taken from the library) has a size of 200x300, then you demand to create a new model that is close in size (of course, if you practice not plan to increase it).

So, the model has been created - in fact it is an empty blank, let'southward at present import the STL model or the model from the built-in library.

• Relief - Import - Import 3D model (STL or OBJ)

Select the STL file, look for the download - and so nosotros prescribe the required dimensions, unchecking the checkboxes, you lot can change the dimensions along the axes separately. You lot tin as well (and if necessary) rotate the model. We identify it in the eye, or as necessary during the project.

So, the model is loaded, now it is bachelor for editing (will be in other lessons) - just now let's await at exporting the model to the ArtCAM relief library, and back to STL.

Salvage the model to the ArtCAM relief library

So, to save the current relief equally a carve up file in the relief library:

• Relief - Export - As file - allows you to salve a model with relief in *. rlf as a divide file with a choice of saving location.
• Relief - Export - To Relief Library - allows you to salvage a model with a relief in *. rlf in its library, which is available with a preview straight from the plan.

If you don't have base model addition files installed, this library will obviously be empty. The library itself is located in the directory:

C:\Users\Public\Documents\ArtCAM Files\Reliefs - here you can also create directories yourself for the convenience of working in the plan and sort the files as yous wish.

In the file library (with add-ons installed) in that location are also a bunch of additional files, templates, vectors and textures.

(When reinstalling Windows, do non forget to save the "ArtCAM Files" directory. After a new installation of the program, just re-create this directory to a new directory on the C drive - all your templates, relief models and other files will exist immediately bachelor from the program).

Now for an example, allow's save the model in the library -

• Relief - Consign - To Relief Library.

Let's reset the relief on the main model (that is, in fact, delete it).

Open up the library and select the previously saved file

The relief is automatically placed on the surface of an empty model, now information technology can be inverse forth 3 axes, increasing or decreasing. By clicking on the lock icon, y'all tin fix the proportions in XYZ or merely in XZ, or remove the fixation of proportions birthday.

Besides, the relief can be changed on the model by stretching or narrowing at the extreme points.

Next, either Insert the relief and it will be fixed every bit a fixed one, or simply shut the electric current window (the relief will remain editable). Re-editing the relief will be bachelor by clicking on the "Transform" button:

The button below will let you to deform the model forth the XY axes, which can be very convenient, for example, when distributing private reliefs along the perimeter of an oval frame.

We make the edited relief active over again (click on it with the cursor) and once again select "Transform" and so "Paste" or "Paste on a new layer" at the bottom correct:

Now the modified terrain can be saved again to the library or as a separate file.

Model conversion from ArtCAM to STL

ArtCAM cannot straight save the model in STL format - the model needs to be converted, that is, to create a triangulated mesh, that is, the same STL.

Select over again:

• Relief - Export - Create Triangulated Mesh.
• Additional options appear (depending on your requirements for the new model).
• Accuracy 0.01 mm (increasing the accuracy to 0.005 mm has almost no effect on the quality of the future STL file, merely increases its size by ~30%).
• One of the main parameters is the smoothing bending. That is, the more than the angle is selected, the more abrupt corners will be blurred (smoothed) on the current model). It is selected empirically (I apply an angle from 20 to 60, depending on the model and requirements).
• Then, the parameters are set - click "Create".
• If necessary, you can alter the Options and recreate the mesh without endmost the current window.

If everything suits you, save the file in one of the formats. I use mostly standard binary STL, only can be saved to ASCII (text) STL or OBJ. So there are some other formats, but I will not consider these extensions here, since I myself accept never used them.

Standard (binary) STL is the best pick for me.

ASCII (text) STL - this file will weigh most 1.8 times more than the previous ane (I did not see whatsoever advantages in it).

OBJ - the file can be opened in most 3D editors. OBJ can also be opened when importing models (similar to STL files).

Import and export bitmaps (height maps, grayscale)

Practically everyone who has worked at least a little in the ArtCAM program knows that to create a relief in the plan, you can use grayscale images, or the so-called tiptop maps, grayscale, grayscale, Grayscale. How to search for such pictures and how to enhance the relief from them is described in particular in this article on the site.

But is information technology possible to relieve the model in this format, that is, save it not equally STL merely equally a grayscale image - yes, of course yous tin. We return to the model on the primary screen (to close the STL model created above, just click on the icon over again, or close the window with a cross).

Next choose:

• Relief - Consign - As File;
• Next, select the file format;
• Either "Windows Bitmap (*.bmp)";
• Or "sixteen-scrap TIFF graphic (*.tif)".

The number of points in both files will be equal to the initially selected resolution, that is, the resolution of the model (in the instance, the maximum 4000x4000 is selected).

Amount of files in megabytes when saving (exporting):

• in *. bmp volition weigh - about fifteen MB;
• in *. tif - most 30 Mb;
• in *. stl - about 100 Mb;
• in *. obj - almost 240 MB.

The saved file (meridian map in grayscale) tin can be edited in any bitmap editor like Photoshop, Gimp, and then raised from information technology again. How to enhance a relief from such pictures is described in detail in this article.

This is the dazzler that turns out (beneath is the screen, the full-size pic has the same resolution as the initial model, that is, 4000x4000 p):

In determination, the large size of the loaded models, besides as the selected high initial resolution of the working model, consumes a big amount of RAM, so the program may freeze and sometimes crash on weak computers. In gild non to lose information, information technology is worth saving the model more oft. By the way, the program can also crash but when performing sure actions - keep in mind. Possibly this is due to the individual settings of the installed Windows, or maybe with software errors.
