Getting started/id

Pendahuluan
FreeCAD adalah aplikasi parametrik modeling CAD/CAE. FreeCAD masih dalam tahap awal pengembang, jadi jangan berharap dapat menggunakannya untuk menghasilkan pekerjaan seperti aplikasi CAD yang telah populer.

Tapi, jika kamu ingin tahu seperti FreeCAD itu dan fitur apa saja yang sedang dikembangkan, Anda dipersilakan untuk mengunduhnya dan mencobanya. Pada saat ini, banyak fungsi yang sudah ada, tapi masih banyak antarmuka pengguna yang belum dibuat. Namun jika kamu tahu sedikit tentang Python, kamu akan mampu menghasilkan dan memodifikasi geometri yang kompleks dengan relatif mudah. Jika tidak, mungkin kamu akan menemukan bahwa FreeCAD masih belum sempurna untukmu. Tapi, bersabarlah, hal ini diharapkan segera berubah.

Dan jika setelah mencoba kamu punya saran, ide atau opini, silahkan dibagi dengan kami di FreeCAD discussion forum!

Instalasi
Pertama (jika belum) unduh dan instal FreeCAD. Lihat halaman Download untuk informasi tentang versi terbaru dan updatenya. Terdapat paket instalasi siap pakai untuk Windows (.msi), Ubuntu & Debian (.deb), openSUSE (.rpm) dan Mac OSX. See the Instal page for information about how to install FreeCAD.

Explorasi FreeCAD


FreeCAD adalah aplikasi 3D modeling untuk semua kebutuhan, difokuskan pada teknik mesin dan bidang terkait, seperti spesialisasi teknik lain atau arsitektur. Hal ini dijadikan dasar sebagai platform untuk mengembangkan berbagai jenis aplikasi 3D, tetapi juga untuk melakukan tugas-tugas yang sangat spesifik. Untuk tujuan itu, antarmuka dibagi menjadi beberapa Workbenches. Workbenches memungkinkan untuk mengubah isi antarmuka untuk menampilkan semua dan hanya alat yang diperlukan untuk tugas tertentu, atau kelompok tugas.

Antarmuka FreeCAD dapat digambarkan sebagai wadah yang sangat sederhana, dengan menu bar, area tampilan 3D, dan beberapa panel samping untuk menampilkan gambaran isi atau properti obyek. Semua isi dari panel ini dapat diubah tergantung pada workbench.

Ketika kamu mulai FreeCAD untuk pertama kalinya, kamu akan disajikan sebuah workbench "umum", yang kita sebut "complete workbench". Workbench ini hanya menampilkan alat yang paling matang dari workbenches lainnya. Karena FreeCAD cukup muda dan belum digunakan untuk pekerjaan yang sangat khusus, workbench ini sangat berguna untuk menjadikan FreeCAD lebih mudah. Pada dasarnya, semua alat disini sudah cukup baik untuk menghasilkan geometri.




 * 1) The 3D view, showing the contents of your document
 * 2) The tree view, which shows the hierarchy and construction history of all the objects in your document
 * 3) The property editor, which allows you to view and modify properties of the selected objects
 * 4) The report view (or output window), which is where FreeCAD prints messages, warnings and errors
 * 5) The Python console, where all the commands executed by FreeCAD are printed, and where you can enter python code
 * 6) The workbench selector, where you select the active workbench

The main concept behind the FreeCAD interface is that it is separated into workbenches. A workbench is a collection of tools suited for a specific task, such as working with meshes, or drawing 2D objects, or constrained sketches. You can switch the current workbench with the workbench selector (6). You can customize the tools included in each workbench, add tools from other workbenches or even self-created tools, that we call macros. Widely used starting points are the PartDesign Workbench and Part Workbench.

When you start FreeCAD for the first time, you are presented with the start center. Here is what it looks like for version 0.16:



The Start Center allows you to quickly jump to one of the most common workbenches, open one of the recent files, or see the latest news from the FreeCAD world. You can change the default workbench in the preferences.

Navigasi di Area 3D
FreeCAD memiliki tiga mode navigasi berbeda yang tersedia, yang dapat diatur dalam dialog pengaturan preferensi atau diubah dengan mengklik kanan dalam tampilan 3D. Untuk informasi lengkap tentang mode, lihat Mouse Model page. Untuk mode default ("CAD Navigation"), perintah adalah sebagai berikut,

Holding down allows the selection of multiple objects.
 * Pan_text=Hold the middle mouse button, then move the pointer.
 * Pan_mode_text=Pan mode: hold the key, press the right mouse button once, then move the pointer.
 * Zoom_text=Use the mouse wheel to zoom in and out.

Clicking the middle mouse button re-centers the view on the location of the cursor.
 * Zoom_mode_text=Zoom mode: hold the and  keys, press the right mouse button once, then move the pointer.
 * Rotate_view_text=Hold the middle mouse button, then press and hold the left mouse button, then move the pointer.

The cursor location when the middle mouse button is pressed determines the center of rotation. Rotation works like spinning a ball which rotates around its center. If the buttons are released before you stop the mouse motion, the view continues spinning, if this is enabled.

A double click with the middle mouse button sets a new center of rotation.
 * Rotate_view_mode_text=Rotate mode: hold the key, press the right mouse button once, then move the pointer.
 * Rotate_view_alt_text=Hold the middle mouse button, then press and hold the right mouse button, then move the pointer.

With this method the middle mouse button may be released after the right mouse button is held pressed.

Users who use the mouse with their right hand may find this method easier than the first method. }}

First steps with FreeCAD
FreeCAD's focus is to allow you to make high-precision 3D models, to keep tight control over those models (being able to go back into modelling history and change parameters), and eventually to build those models (via 3D printing, CNC machining or even construction worksite). It is therefore very different from some other 3D applications made for other purposes, such as animation film or gaming. Its learning curve can be steep, especially if this is your first contact with 3D modeling. If you are struck at some point, don't forget that the friendly community of users on the FreeCAD forum might be able to get you out in no time.

The workbench you will start using in FreeCAD depends on the type of job you need to do: If you are going to work on mechanical models, or more generally any small-scale objects, you'll probably want to try the PartDesign Workbench. If you will work in 2D, then switch to the Draft Workbench, or the Sketcher Workbench if you need constraints. If you want to do BIM, launch the Arch Workbench. If you are working with ship design, there is a special Ship Workbench for you. And if you come from the OpenSCAD world, try the OpenSCAD Workbench.

You can switch workbenches at any time, and also customize your favorite workbench to add tools from other workbenches.

Working with the PartDesign and Sketcher workbenches
The PartDesign Workbench is specially made to build complex objects, starting from simple shapes, and adding or removing pieces (that we call "features"), until you get to your final object. All the features you applied during the modelling process are stored in a separate view called the tree view, which also contains the other objects in your document. You can think of a PartDesign object as a succession of operations, each one applied to the result of the preceding one, forming one big chain. In the tree view, you see your final object, but you can expand it and retrieve all preceding states, and change any of their parameter, which automatically updates the final object.

The PartDesign workbench makes heavy use of another workbench, the Sketcher Workbench. The sketcher allows you to draw 2D shapes, which are defined by applying Constraints to the 2D shape. For example, you might draw a rectangle and set the size of a side by applying a length constraint to one of the sides. That side then cannot be resized anymore (unless the constraint is changed).

Those 2D shapes made with the sketcher are used a lot in the PartDesign workbench, for example to create 3D volumes, or to draw areas on the faces of your object that will then be hollowed from its main volume. This is a typical PartDesign workflow:


 * 1) Create a new sketch
 * 2) Draw a closed shape (make sure all points are joined)
 * 3) Close the sketch
 * 4) Expand the sketch into a 3D solid by using the pad tool
 * 5) Select one face of the solid
 * 6) Create a second sketch (this time it will be drawn on the selected face)
 * 7) Draw a closed shape
 * 8) Close the sketch
 * 9) Create a pocket from the second sketch, on the first object

Which gives you an object like this:



At any moment, you can select the original sketches and modify them, or change the extrusion parameters of the pad or pocket operations, which will update the final object.

Working with the Draft and Arch workbenches
The Draft Workbench and Arch Workbench behave a bit differently than the other workbenches above, although they follow the same rules, which are common to all of FreeCAD. In short, while the Sketcher and PartDesign are made primarily to design single pieces, Draft and Arch are made to ease your work when working with several, simpler objects.

The Draft Workbench offers you 2D tools somewhat similar to what you can find in traditional 2D CAD applications such as AutoCAD. However, 2D drafting being far away from the scope of FreeCAD, don't expect to find there the full array of tools that these dedicated applications offer. Most of the Draft tools work not only in a 2D plane but also in the full 3D space, and benefit from special helper systems such as Work planes and object snapping.

The Arch Workbench adds BIM tools to FreeCAD, allowing you to build architectural models with parametric objects. The Arch workbench relies extensively on other modules such as Draft and Sketcher. All the Draft tools are also present in the Arch workbench, and most Arch tools make use of the Draft helper systems.

A typical workflow with Arch and Draft workbenches might be:


 * 1) Draw a couple of lines with the Draft Line tool
 * 2) Select each line and press the Wall tool to build a wall on each of them
 * 3) Join the walls by selecting them and pressing the Arch Add tool
 * 4) Create a floor object, and move your walls in it from the Tree view
 * 5) Create a building object, and move your floor in it from the Tree view
 * 6) Create a window by clicking the Window tool, select a preset in its panel, then click on a face of a wall
 * 7) Add dimensions by first setting the working plane if necessary, then using the Draft Dimension tool

Which will give you this:

Scripting
Dan terakhir, satu dari banyak fitur yang paling handal di FreeCAD adalah scripting. Dari integrasi konsol python (atau dari eksternal skrip python yang lain), kamu dapat mengakses ke hampir semua bagian dari FreeCAD, membuat atau modifikasi geometri, memodifikasi representasi dari objek - objek dalam tampilan 3D atau akses dan memodifikasi antarmuka FreeCAD. Python scripting juga dapat digunakan dalam macro, yang menyediakan metode yang mudah untuk membuat perintah sesuai keinginkan kita.

And finally, one of the most powerful features of FreeCAD is the scripting environment. From the integrated python console (or from any other external Python script), you can gain access to almost any part of FreeCAD, create or modify geometry, modify the representation of those objects in the 3D scene or access and modify the FreeCAD interface. Python scripting can also be used in macros, which provide an easy method to create custom commands.
