Now you have a sketch that is in 2D. In order to turn it into a solid 3D part, you have to extrude it. You can extrude a part in three possible ways.
One way is to right click on the sketch and select “Extruded”.
The other way is to go the menu on the upper bar, select “Shape” and select “Extruded” in the list of the available options.
The easiest and simplest way, especially when you get familiar with the software, is to select directly the “Extruded” button from the menu bar, as indicated by the red arrow in the following picture.
No matter how you choose to do it, when you enter the extruder mode it looks as in the following picture. If the “Surface” box is checked, you have to uncheck it so that your model is extruded as a solid part, and not only as an outline.
Also, enter the height of the extrusion and unbox the “center” option, so that the extrusion is distributed only towards one direction. Now you can validate.
Your 3D model should look like this:
A very useful tool when designing a 3D model is the “drilling” tool. With that, you can create holes in your solid 3D model. With TopSolid software, using the drilling tool is particularly easy when you’ve already designed some circles while sketching. You can activate the “drilling” tool in two ways.
The first way is to right click on the surface of your 3D part where you want to create a hole and select “Drilling”.
Otherwise, you can go to the upper toolbar and select “Drilling” as indicated in the following picture.
Now, select the place of your 3D design you want to place the hole on.
Now, you can define more of its parameters. First of all, it is design-wise to select the “Through” option instead of any other, because this setting enables you to apply a hole through the whole height of your 3D part, even if you change its thickness. Moreover, you can define the diameter you want your hole to be.
You can apply
The result after two drillings should look like this:
Now let’s hollow this 3D model and apply a uniform wall thickness to
Now, let’s undo the “drilling” from the previous steps and bring back the part to its solid form. It should look like this:
In order to
To do so, right click on the desired surface and then go to the upper toolbar and select the “Hollow” tool.
In the window that will appear, enter the value of the depth that you want your shell to be. Though, mind the direction of the
Now, validate and it’s done!
Alternatively, you can hollow your part from a different surface. Or even hollow your part selecting multiple surfaces. Let’s see how is this possible.
Undo the “hollowing” command to return to the initial solid shape of your part. Now right click on two different surfaces by pressing the “Ctrl” button, and select “Hollow”.
On the new window that appears, select both the surfaces to be
Press validate and your model should look like this:
You can add some fillets to your design to make the sharp edges smoother. To do that, select the “Fillet” button from the upper toolbar.
Now select the edges that you want to smooth, and enter the value of the radius. If you want all your edges to have the same fillet, click on the “Identical” box.
Validate, and your 3D part should look like this:
If you want to add some chamfers to your design, select the “Chamfer” button from the upper toolbar.
The procedure is the same as adding the fillets. Select the edges that you want to chamfer. On the window that appears on your left, enter the value of the chamfer and select the “Offset” mode.
You can select multiple edges to chamfer at the same time, simply by left clicking on them.
Once you validate, your 3D printed part should look like this:
