Replicating objects on Onshape

Does anyone have any detailed, simple instructions as to how to to replicate a rook like the one of the link below:

If you want the masonry look on cylindrical and conical faces, as shown, it seems to me your instructions are unlikely to be both detailed and simple.

Everything else is straightforward.

Simple profile sketch & revolve gets you pretty close but masonry details will take some time to perform. Very good project to get into 3d / Onshape world

If I needed to replicate this (in/outside), I would probably model tile and use circular pattern, this would also produce more realistic data what is needed to build one (from bricks not 3dprint)..

After much consideration, I've decided to keep all of my chess pieces uniform with a simple design.

I already have the base and a cylinder on top, but I don't know how to make it "slanted", as well as the top part of the rook.

I'll probably be asking more questions in the future regarding chess pieces, so stay tuned!!!
Thank you to all who have helped so far

Make a sketch of 1/2 the profile like so.








Then revolve like so.

See video and link >> ( Rook ) for the slots.

This forum is amazing, nothing to add @DaVicki 's great representation.

Thank you so much, that was amazing!!

Just another quick question: does anybody know how to do the upper part of the bishop?

I have no problem building the foundation, but I've been having the same problem with my pawn, with the sphere on top.

Looking at the bishop, it is mostly the same profile revolved around the enter axis and then an angled rectangle taken out of the top.

I would suggest uploading the image you attached to your onshape document and then inserting it into a sketch.

1. Upload the file to your document.  Start a sketch and select insert image.


2. The insert image dialog will pop up and you select the file name.  This will allow you to sketch a rectangle of what you want.


3. Sketch the rectangle that bounds your image.  I like symmetry so I tied the rectangle to be about the origin.  I did this by selecting the origin first, then two opposite corners and chose mid-point.  This forces the origin to be half-way between the two points.  I then sketched a vertical line for my axis of revolution (and dimensioned it to get some idea of scale).  From here I made a horizontal line on the bottom for a base then used a single spline to trace the outline of the bishop.  Mine was a bit rushed and sloppy, but is editable.


4. Revolve the profile you created about the vertical line.  This will create the majority of the bishop.


5. Because we revolved about a line tied to the origin, I decided to use one of the default planes to cut away at the top.  I sketched on the front plane and made a construction line that was about the center then made perpendicular lines to make a region.


6. Extrude the profile in both directions through all and set the type to remove.  This will cut away at the top.


The result is more or less a bishop.



Because this is something somewhat artistic, I mostly eye-balled everything.  While no one has ever confused me with being an artist, it is a quick and easy way to trace something.  If you are hoping for specific dimensions then you can go about and add dimensions.  Likewise, if you don't want the thing to be just one spline you can break up the profile into lines, splines, and arcs.

How can I apply the same technique for the rook?

When we have a full Set, anyone fancy a game

Does anyone have any idea on how to replicate the knight:

I'm almost done the chess set, just have to figure out how to replicate the knight and queen.  A little help please!

øyvind_kaurstad

Replicating the knight is certainly possible, but it will be a bit of work. The base is just a simple revolve, the upper part is a little more work. I think I would start by drawing a side profile, then extrude that symmetrically to the width of the upper part of the base. Then create a new sketch to extrude remove from the sides to have the tapered shape from the base and to the top. Then you'd just have to create the rest of the features with various sketches and extrudes/sweeps to carve out of the base shape. Just remember that you can mirror from one side to the other.  :-)

There is no (very) quick way to do this, it will be some work until you get it right, or at least close enough. The devil is in the details on this one, the base shape is quick and easy as I described.

irene_rivers

Alright thanks!  Are there any other ideas to tackle this project (knight)?  
I realize that it will take some adjustments because you can't simply revolve half of the image.

How about the queen:

I know that I'll have to revolve around the base, but would I have to trace the outline of only half of the picture; this is using the same technique that was mentioned earlier in this discussion.

irene_rivers

Does anyone know an easier method of replicating the knight?
I haven't tried this yet, but I'm planning on drawing half of the top of the knight, revolve it, and then glue both halves together to form the top part.
At the moment, I don't think I'll be printing the knight in one shot.

irene_rivers

I've completed my chess set now.  All I need to to is print out the chess board itself and make sure that it interconnects between each piece!
Any ideas on how to make that?  I found someone else's files and I'm planning on printing that, but I'd like to try creating one myself.

3dcad

Why print, just create assembly with planar mates to the board and share with another player

ps. Is this project public? I would like to actually try online game in Onshape..

@3dcad now that's a cleaver concept,  Onshape board games!!

irene_rivers

I'll make my pieces public, so feel free to use them  
I can't take the credit for the rook and knight because I used files from thingverse.
Everything else are my own pieces.
I'm not sure how to make the chess board, although I did find some cool files on thingverse.
Any ideas?  A little help please.

@irene_rivers
Without any further thinking I would say draw a square, extrude to part and use pattern to create a board from many pieces, then use part color to make it chess board.

Can you please share a link to your project?

irene_rivers

Now that's pretty simple, but I was thinking of interconnecting the pieces to stabilize it.
They're on different documents, but here you go:
