FREECAD 2D SOFTWARE

Once you have the coil, it will need some kind of terminals

Click Sweep Path and select all of the path lines (B) in the 3D viewfinder holding Ctrl.

Select the sketch which will be your profile (A) and check create solid and frenet if the profile is not a circle.

You can change the sketch position in it's properties.

Create a sketch of the desired profile and position it at the beginning of the helix.

Create a helix or spiral to the desired dimensions with Create parameterized primitive in part workbench.

If you need to create a coil inductor, you will probabaly use the Sweep tool, which can be found in the Part workbench. To use boolean you must first select the active (A) body, and then the tool body (B, C) Creating coil inductors ( Sweeping)

Click on the little expression button and write Spreadsheet.alias, for example, Spreadsheet.Terminal_lenghtīoolean is a very powerful tool used for combining or splitting objects that comes in many types: Union, Cut, Difference and multiple others.

Go the property you want to apply the parameter to.

Right click the dimension cell, go to Properties → Alias and give it an alias.

Write the dimension, for example, as = 35mm.

Create a variable name for the Property in column A.

Create a spreadsheet in the spreadsheet workbench.This works both with objects such as extrude, or sketch dimensions. In FreeCAD you can create a spreadsheet to parametrically determine An objects properties. In most cases you can extrude, revolve or sweep a sketch.Įxample of a model created with extrusions, and revolveįreeCAD is a parametric modeler like many other CAD programs, so you can change the parameters of an operation in the properties on the left or you can edit the base sketch afterwards. To move a sketch, for example, on the end of a coil, use the position parameters in propertiesĮxample of a sketch created for extruding:ģD modelling in FreeCAD can be done in the Part workbench.Ī primitive object can be created using the yellow primitive solids, but usually the most efficient way to create the desired object is to start from a sketch.When working on a face sketch, use Create edge linked to external geometry.If you want to create a sketch on a surface of an object, select the face and then create sketch.If you can't constrain or position an object, use Construction lines.Left click-hold and drag lines or points around, to see missing constraints.It should be straight-forward creating them, but here are some tips to help you along: These sketches will be created in the Sketcher workbench. Merge the created sketches into one by going into Sketcher workbench, then Sketch → merge sketch.ĢD sketches can be used solely for 2D simulations or as a basis for further 3d operations such as extrude, revolve or sweep.Convert the lines to a sketch by going into Draft workbench, then Draft → Draft to sketch.Delete unnecessary elements before the next steps.DXF drawing for further modification, there will be a few steps: If you wish to import, for example, a 2D.

(Same as rotate 1) Hold the middle mouse button, then press and hold the right mouse button, then move the pointer.įreeCAD can import the following formats: STEP, IGES, OBJ, STL, DXF, SVG, STL, DAE, IFC or OFF, NASTRAN, VRML Hold the middle mouse button, then press and hold the left mouse button, then move the pointer.

Clicking the middle mouse button re-centers the view on the location of the cursor. Hold the middle mouse button, then move the pointer around. Press the left mouse button over an object you want to select. But here are a few examples:įreeCAD is a very universal piece of software, and has many workbenches which are different work environments with different tools for various applications, but we will mainly use Sketcher, Part and Part Design. With FreeCAD will be able to create much more complex geometries than covered in this guide.

FREECAD 2D SOFTWARE

You can use any CAD software to prepare STEP files but FreeCAD will allow you to create 3D geometry from scratch, or use your 2D cad files as a base.įreeCAD has most of the features of ther CAD programs, such as most of the modeling tools and parametric design, all of which make modelling quick and easy, saving you time and money. The main purpose of FreeCAD is to create a STEP file for CENOS. With the help of this short guide of FreeCAD, hopefully, you will be able to quickly create advanced geometry for your simulation cases.įreeCAD download: What you can create with FreeCAD FreeCAD is a completely free, open source CAD modeler which you can use to create 2D or 3D geometry for your simulations.
