Making Drawings With Onshape Service

Image
Here are my first drawings made with Onshape.com online service. These drawings are simple details used for educational purpose. Here is my personal part number system. S1-M-0915-02 S1-first year of study M-misc. (can be: A-architectural, J-jewels, P-can be 3D printed, W-wooden, F-furniture.) 0915-date 02-part number

Vase in Salome-Platform

Image
Here is my model of a vase. 1) Use operation "revolution" to make vase. 2) Make curved surface in order to create the spiral. (Surface should go through the vase.) 3) Use operation "thickness" to make the surface a solid. 4) Apply operation "partition" using the curved solid as tool. 5) Explode the partition into solids. 6) Select the curve and use operation "scale" to lengthen it. (You can also explode the curve into faces, fuse the surface faces, and extrude them to achieve the same result.) 7) Use operation "multi-translate" to copy the curve around the vase. 8) Use operation "cut" to create final shape. The model was built in millimeters, but STEP understands only meters. The model was scaled by 0.001 to convert into meters. Your browser does not support iframes.

David Star Ring in Salome-Platform

Image
Here is my model of a ring with a David star. This star was made using operation "filling." During the process, the star and the circular base were not partitioned correctly. That is because the planes that were used as tool objects did not intersect the vertices of the star. The problem was was fixed by connecting the edges and building them into a wire. Here is the new archive.

Star Ring in Salome-Platform

Image
Here is my model of a ring. The star was made using operation "filling." The result is a smooth transition from the circular base to the star shape. Then the star was built into a solid and fused with the ring. Fillets were applied to smooth edges. The ring was scaled to meters. During the process there was failure to build closed solid. The problem was fixed by closing the gap in the wire. Here is the new archive.

Moai Head Statue in Salome-Platform

Image
Here is my first attempt to make moai anthropomorphic statue. Here is the model. Here is the STEP file. The head is made from a partitioned cylinder. The nose is made from a cone. The mouth is made using operation "extrusion along path." The ears were sketched and extruded. Here is the reference picture.

Shampoo Bottle in Salome-Platform

Image
Here is my model of a shampoo bottle. The bottle was made using operation "filling." Operation "scale" was used to achieve the desired shape. Here is the new archive.

Corrected Bar Stool in Salome-Platform

Image
Here is the model of the corrected stool. These are the following corrections: The legs of the stool are thiner (1inch in diameter). The legs were rotated to provide broader base of support. (That means that when a person shifts the center of gravity, the chair will not fall.) The pointy back of the char was cut to create a smooth curve.

Bar Stool in Salome-Platform

Image
Here is my model of a bar stool. The seat was designed in DraftSight and made using operation "filling." The legs were made using operation "extrusion along path." Dimensions Height:47" Width:40" Depth:38"

Jug in Salome-Platform

Image
Here is my model of a jug. The jug was made using operation "revolution." The handle was made using operation "extrusion along path." The nose of the jug was made using a cone. The shape of the top was made by building a face of desired shape. (The face was built by creating lines, and extruding them to create surface.) The resulting face was used as tool object in operation "partition." After the partition was exploded, the desired solid was fused with the jug. The jug was then exploded into faces and then scaled to create thicness. (You could include thickness of the jug in the wire, before using "revolution", to avoid scaling.) Operation "fillet" was used to smooth edges.

Bear Model in Salome-Platform

Image
Here is my model of a bear. The body of the bear was made using operation "revolution." The body parts were made out of scaled spheres. Fillets were applied to smooth the edges. Operation "mirror" was used to create symmetry. Here is the new archive.

Bottle in Salome-Platform

Image
Here is my model of a 1 gallon bottle. Make bottle using operation "filling." Close the filling with faces and create solid. Next, create a solid in order to cut the handle. Position the solid in appropriate place and use operation "mirror" to copy it to the other side. Leave some space between the solids to make handle. Cut the bottle using the two solids as tool objects. In order to cut hole in the handle, create wire on both sides using the edges of the cut. Create faces between the wires using operation "filling." Fuse the faces and use that as tool to partition the bottle. Explode the partition to get the final bottle with handle. The volume of the bottle after last operation was 268.48 cubic inches. 1gal=231cub. inch. The scale ratio to get 1 gallon is found by formula. (268.46/231)^(1/3)
