In this essay we are going to tell we how to modify 3D indication into a genuine indication that we might cut with we CNC appurtenance or laser cutter.

Let’s make this Christmas tree

Slicing of a indication for CNC machining regulating a piece material.

Run 3ds max.

To equivocate a dimensions units difficulty use millimeters. Go to a Customize Units Setup in a menu. In a Display Unit Scale section of a non-stop Units Setup dialog box, name a Metric button and name millimeters from a drop-down list. Click a System Unit Setup button. In a non-stop window name millimeters. Click Ok.

Import of a model

Click a focus symbol and name Import.

Select a required record and click Open.

Depending on a record extension, a window with settings will appear.

When importing from STL, in a Import STL File dialog box in a Weld Vertices section, name a Quick Weld switch. This will severely accelerate a import.

Сheck a indication for a surfaces intersection.

Select a indication and make it unclouded by dire Alt + x.

On a front perspective emanate a territory Create Shapes Section

The surfaces intersections are good seen now.

Delete a intersections.

Select a fir-tree image.

Convert a indication to Editable poly by right clicking a perspective window (Convert to Editable Poly).

By clicking a 5 pivotal go to a mode of a elements selection. Select a case of a tree and click Detach in  a Edit geometry toolbar.

Do a same with a star. Now we have 3 apart objects.

Combine them regulating a boolean operation.

Select a fur-tree and Create Compound ProBoolean

In a Parameters of a toolbar switch to Union.

Click Start Picking. Select a star. Once again click Start Picking to finish a intent selection.

Now a indication does not have intersecting surfaces.

Bring a indication to a distance we need, so that a tallness becomes 10 cm.

Create a box Create Standard primitives Box.

In a toolbar Parameters set a Height at 100 mm

Click a R pivotal to name a Scale tool. Adjust a distance of a fur-tree so that it touches a tip craft of a box.

Slice a model.

Set a grid spacing equal to a covering thickness. Right-click a Snaps toggle button. In a Grid and Snap Setting dialog window find  a Home Grid tab, and set a Grid Spacing at 4mm; In a Snaps tab check a Grid Points checkbox.

To capacitate bindings, left click a Snaps toggle button. The symbol gleams blue.

Create a territory in a front perspective Create Shapes Section. On a tip perspective place a territory craft in front of a model. Move a craft one block to a indication and click a Create Shape button. In a Modify tab of a toolbar change a craft one by one block by clicking Create Shape until we have finished a whole model.

You will get something like this:

Hide a fur-tree. Select a ensuing curves and request a Extrude modifier to them.

Delete a additional outlines.

Select one covering and click Editable Spline in a modifiers. Click a 3 pivotal to change to a spline preference mode. Delete a additional outlines.

Save a outlines for a G-code generation.

Select all a layers and undo a Extrude modifier. To do it right click in a modifier smoke-stack and name Delete in a context menu.

Position all a outlines in one plane, get them together and hang in a support 160х160 mm.

Export a outlines to DXF.

Select all a outlines and click a focus symbol Export Export Selected. In a Save as form choose  AutoCAD (*.DXF). The trade parameters leave as default.

For G-code era use Inkscape (https://inkscape.org/ru/download/)

and JTP Laser Tool. (https://jtechphotonics.com/?page_id=1980)

As Inkscape doesn’t support DXF, modify it to SVG regulating a giveaway online use https://www.dxfconverter.org

Run Inkscape. Set mm as dimensions units.

Import your outlines.

It is probable to drag a SVG record to a Inkscape canvas. To see a outlines set their density larger than 0, during 0,1 mm for example.

To move a distance of a outlines to a genuine ones emanate a rectangle identical in distance to a support around a outlines, i.e 160x160mm. Now scale a support with a outlines so that a support coincides with a rectangle. Remove a support and a rectangle.

Now beget a G-code.

Go to  Extensions Generate Laser Gcode JTech Photonics Laser Tool.

Laser ON Command, Laser OFF Command; Travel Speed is a speed with a laser off; Laser Speed is a speed with a laser on; Laser Power (255 corresponds to 100% of a power); Power On Delay is a check of a laser start; Passes is a series of a laser passes; Pass Depth is a laser downshifting after any pass.

Specify in a Catalogue where to save a G-code to.

To start a G-code era click Apply. Shortly we will see a G-code record there.

Hope that we enjoyed this guidance.
