Modeling Skinny Walled Elements | TriMech Coaching Tidbits

SOLIDWORKS is the most well-liked CAD software for mechanical engineering and product design. Studying how one can use it successfully is crucial to thousands and thousands {of professional} CAD customers. TriMech’s instructor-led coaching is a good way to be taught SOLIDWORKS shortly.

I’ll information you thru the method of modeling a skinny walled half that features a revolved characteristic. Particularly, one thing most of us want throughout our workday, a ceramic espresso cup! The instruments and methods proven listed below are from the half modeling classes within the SOLIDWORKS Necessities class. The espresso cup is loosely based mostly on one in every of my favourite glass mugs, which is totally unsuitable for warm drinks.

Key Takeaways for Modeling Skinny Walled Elements

Within the technique of modeling this half, we’ll cowl:

• Open Profile Sketches
• Doubled Dimensions
• Convert Entities in a Sketch
• Revolved Options
• Swept Options
• Skinny Options
• Full Spherical Fillets
• Supplies & Appearances

Open Profile Sketches and Doubled Dimensions

The sketch proven under, created on the Entrance Airplane, is what we’ll use to create the principle physique of the espresso cup. The three dashed development strains won’t extrude to create a 3D mannequin. Solely the three stable strains and the 2 sketch fillets connecting them will extrude. Discover the realm isn’t shaded as a result of the development strains don’t rely as a part of the sketch contour. So, that is an open profile sketch.

The 2 diameters are doubled dimensions. The trick to creating them is having a middle line (aka development line) to dimension to. Utilizing the Sensible Dimension instrument, choose the centerline and one other entity (comparable to a line, level, and so forth.). Earlier than you place the dimension, transfer your cursor to the alternative aspect of the middle line from the opposite entity. The dimension will robotically be doubled.

Modeling Revolved Options and Skinny Options

Now we are able to launch the Revolved Boss/Base command. A pop-up will seem to warn us that the sketch profile is open. It is going to ask us if we wish the sketch to be robotically closed. If we choose Sure, it’s going to alter the sketch to make it a closed profile. If we choose No, the Skinny Function part of the Property Supervisor can be activated.

First, let’s take care of the necessities of any Revolved Function. The Course defaults to Blind and 360°, so the contour can be revolved all the best way round a central axis. If just one middle line exists in a sketch, it’s going to robotically be chosen because the Axis of Revolution. If there are a number of middle/development strains within the sketch, as is the case right here, we’ll have to pick which one we wish to use.

Creating the revolved characteristic for a skinny walled half

Second, let’s take a look at the extra controls for a Skinny Function. Extruded Bosses and Cuts can use the Skinny Function performance, whether or not the sketch is an open or closed profile. When the Skinny Function part of the Property Supervisor is activated, sketch entities can be given a specified thickness as they extrude. We are able to select so as to add this thickness to both aspect of the entities, or a unique quantity to every aspect, or choose the Mid-Airplane choice as proven under.

Utilizing Convert Entities for the Mannequin Base

Now that we now have the cup form with a wall thickness of 1/4 inch, it’s time so as to add the bottom. We’ll make it good and huge as a result of no one needs spilled espresso.

We’ll begin a brand new sketch on the Prime Airplane. What we wish is a circle that precisely matches the higher fringe of the Revolved Function. Choose the sting after which click on Convert Entities on the Sketch tab of the Command Supervisor.

Utilizing the Convert Entities command to make the bottom

A brand new circle entity can be created, projected into the sketch from the mannequin edge. An On Edge sketch relation will be sure that it stays the identical as the sting it was created from. (If you choose a face to transform, all its edges can be projected into the sketch.) This ensures that if we modify the outer diameter sooner or later, the bottom will change to match.

Now we are able to create an Extruded Boss. We’ll give it the identical 1/4 inch thickness because the Revolved Boss. Use the Mid Airplane finish situation in order that we’ll get 1/8 inch extruded above and under the sketch airplane. That may be sure that we don’t get any sudden gaps in geometry because of the angled aspect of the cup.

Making a Path Sketch for a Swept Function

We want a sketch to outline the cup’s deal with. For the reason that deal with must be connected to the wall of the cup, we are able to choose Sketch1 within the Function Tree and click on Present within the Context Toolbar. To make Sketch1 stand out higher, right-click it within the Tree and choose Sketch Colour from the Context Menu. Choose a shade, comparable to magenta, which is able to stand out higher.

The trail sketch for a sweep proven in magenta

Now we are able to create a brand new sketch on the Entrance Airplane. As proven above, it’s going to include a horizontal line, an arc, one other line, and one other arc. That is one other open profile sketch with the higher and decrease endpoints connected to strains in Sketch1 with Coincident relations. Dimensions and geometric relations can then be added to completely outline the deal with form.

Extruding a Swept Function with a Round Profile

The brand new sketch would be the path of a Swept Boss. When creating this kind of characteristic, we take a cross-section profile and sweep it alongside the trail.

There are two Profile choices within the Sweep Property Supervisor: Sketch Profile and Round Profile. In both case, we have to specify our path sketch within the acceptable subject.

Utilizing a round profile for a Swept Function

If we wish a easy round cross-section, we are able to simply give it the diameter worth and hit OK. If we wish every other cross-section, we now have to create a profile sketch first. Right here we simply need 1/2″ diameter for the circle, so we solely want one sketch.

Creating Fixed Measurement Fillets

Our sketch-based options are carried out, however we’d like fillets to spherical off sharp edges. We want two Fixed Measurement Fillet options, as proven within the Part View under.

Quarter and half-inch fillets on the mannequin

Half-inch radius fillets are added between the 2 edges the place the Revolved and Extruded Bosses meet. Quarter-inch fillets are added to the 2 edges the place the Swept and Revolved Bosses meet.

Utilizing Full Spherical Fillets for Computerized Dimensions

There are 4 several types of fillets, with many choices obtainable. Fixed Measurement fillets are the commonest. The others are Variable Measurement, Face, and Full Spherical Fillets, the latter of which we’ll use to spherical off the lip and base of the espresso cup.

A Full Spherical Fillet replaces a flat face with a curved one without having to enter dimensions. The Property Supervisor has completely different choice fields for the middle face we’re changing and the faces to both aspect of it. We are able to’t create a number of fillets as a part of the identical characteristic because of the nature of the instrument. So, after rounding off the lip of the cup, we are able to add one other fillet to spherical off the bottom.

Utilizing Full Spherical Fillets to spherical off a flat face

TIP: In the event you faucet the appropriate button instantly after choosing a face, the energetic choice subject can be superior to the subsequent one to save lots of you some mouse journey. After the final choice, faucet the appropriate button once more to complete the command.

Apply Materials Properties to the Cup

Geometrically, the cup is completed. However we are able to nonetheless assign materials properties to the mannequin, together with a extra lifelike look. Proper-click Supplies within the tree, and the Materials dialog field will seem. Browse the database to search out an acceptable one, comparable to Ceramic Porcelain. The brand new materials and look can be assigned to the mannequin after we hit the Apply button.

Making use of a fabric to the mannequin

Edit Look to Tremendous-Tune Appears

There are numerous methods so as to add and customise the looks of a mannequin. All we have to do on this case is give our cup a extra fascinating shade. Click on Edit Look on the Heads-Up Toolbar, then choose a shade from the palette and hit OK.

I went with SOLIDWORKS pink for my espresso cup. To show off the show of the black edges, choose the Shaded Show Model from the Heads-Up Toolbar.
