Modelling question

Post by Phil »

I've started building a 1910 Ford "Tin Lizzie" model. I plan to make some of the parts on my rotary axis. I'm not sure how to model the "block". Also not sure what to call the part.
I've created the one shown here in Sketchup, pretty simple. In Aspire I can easily model to cube shape but I can't figure out how to add the discs on each of the four sides.
I know I can import the Sketchup file into Aspire but I'd like to know how to add the discs in Aspire.

Not quite sure what you're trying to achieve with "adding discs to a cube" and using a rotary. What part are you making?

I'm not sure what this part is called. I think I can make it on the rotary indexer.

That would be a carriage lantern. A hold-over from... umm... carriages. :D

Good to know. My question now is how do I model the cube in the middle. I can easily create a cube but I can only put around disc on one of the sides. I'm looking for help in adding the discs to all four sides.

Phil,
Sometimes it's best, or at least easier to use a different modeling software. I was just guessing at the size, but I did this in Rhino which took about 5-minutes. If you can give me the size, I can do a more actuate model and sent it to you.

Yup Rhino can do it but so can Sketchup as Phil was attempting to do initially.

But, so can Aspire. Here's a few minutes attempt using my limited Aspire knowledge (and the trial version so I can post the file here).

I used the extrude command using a half-circle to create a half-cylinder on the top side, another half-cylinder perpendicular to the first, and the create shape command to create the rectilinear solid from a square. I then copied all three components to the bottom side.

Thanks, gentlemen. I appreciate the help. I'm very early in the project, not sure when I'll get to the lanterns. I just wanted to figure out how to make that part.

I suppose if each of the 4 sides are the same (or in pairs), then take your 4-sided stock and 2-d cut each side (manually turning/flipping 90 degrees following each cut); perhaps?
