right side or top side when drawing?  1-20  21-40  41-60  …  81-92

Here is a very basic question. The object I will be working on will be a 2x6 board 15" long. When I am drawing it in the boxes, I will have the 2x6 laying on its side so the front will be my right side, so the right side of the finished product is the top side when laying on the table, Ok? So when it says top view, is it referring to the top of the finished product or the top as it sits on the machine, which would be the right side when finished? Hope this makes sense??

Thanks

Tony

Hi Tony, usually the Top view means the top as it sits in the machine.

Like if you were sitting at a work bench, the top view would be a view looking straight down on to the tabletop surface of your work bench.

So it sounds like you may want to draw your particular project in a side view instead.

But if you draw it in the wrong view it is not a big deal, you can just rotate it 90 degrees to reorient it. The easiest way to do that is to just select everything and then grab the rotation grip on the edit frame that is on the outside of selected objects:

Thanks. I worked on it last night and now am able to save the file and move it to cut 3D. Thank you.

I am getting closer but I still have a long way to go in drawing the object. Suggestions appreciated.

The wood will be a 2x6 flat side on table and suspended with fixtures so I can turn it over and do the other side. This description might be unclear and I am not sure how to post a picture of what I am trying to make. Hope some of the this makes sense.

The wood, as it goes from left to right will get smaller in the y and Z axis and then flare out wider. The corners will be rounded on most sides with a few curves cut and radiused toward the middle portion.

Tony

It's hard to figure out what you are talking about just from a written description.

If you can attach a picture and also the 3DM model file of your current progress that would probably help a lot.

When you make a new post there is an "Attachments" button that you can click on to make files attached to your post, please see here to see some screenshots of the button and the dialog that pops up:

JFYI,
2 things. It sounds as if he is refering his axis comments about his "Machine table", Like the "Z" may actually be MoI's "x" axis. Then, he is going to cut3d in a poly format, which may have the "Z becomes Y" thing going on...

But, the model will help. I just thought I read that "table axis mismatch" being discussed.

Maybe Tony can inject a bit more about his machine table setup too, to clarify.

Anyway, waiting for the file.

When I am in the shop tonight, I will take a picture of what I am trying to make and try posting it. I will verify the xy on the table. My project is pretty simple but I just am not getting my head around how to do a few steps.

I hope these pictures show up.

The dark wood on the left is what the light color wood needs to be shaped like. The light wood is mounted on fixtures so it can be turned over for the other side. I see it as drawing straight lines to specific distances, then curves with a radius, fillet the sides and much should be done. But I am not getting the fillet or curved portions to turn out. Also having trouble setting the length of straight edge and degree of taper. Any help would be appreciated.

Tony

A couple of simple possibilities, not to scale:
Used rectangle, ellipse, and arc.
Used offset. Move one offset, add line rail, sweep...
The handgrip seems a lot more challenging...

Can you also post the 3DM model file of what you currently have so we can see how you are currently attempting to approach the problem?

Are you starting out with just a box in MoI for your starting shape?

For something that's really curved you probably don't want to start out with a box but instead draw in some curved profiles and then use a surfacing command like Loft or Sweep to generate a surface from those curves.

I'm afraid though that a rifle stock like that is probably going to be a fairly advanced type of project to tackle in MoI mostly because it is a more sculptured type shape and not just defined only by simple 2D profile curves. In order to make sculptured shapes you have to use a more advanced part of the toolset and do more freeform surface construction using lofts and sweeps and things like that.

Thank you so much for the visual aids. When I saw how your approach would be, the tutorial made a lot more sense to me.

I am not concerned to much at this point about the grip region, as getting the back portion shaped will save me a bunch of time while I get used to things.

I did not get a chance last night to work with this, but I will tonight as my brother-in-law will be coming to help as he is familiar with the g codes much more than me for when we start in Mach3.

Thanks again. I will most likely have another question this wkend.

Also, you mentioned posting the codes. What actually do these look like on the screen and how do you post them?

Tony

Are you talking here about the G-code ?

Those are a list of instructions for how to move the cutting tool on your CNC, usually it's a CAM program that will calculate them and show them to you.

I think you called them 3D model codes???

Looking forward to tonight to give this a wkends attention and see where I get.

I'm sorry I don't really know what that's referring to... Maybe just 3D modeling techniques like sweeps and lofts?

Some of those construction techniques like sweeping are covered in the introductory tutorials, have you had a chance to watch those? :

Hi Tony,
Here's a quick example of going from model to code:



You'll see me model a part in MoI then save it to an STL. I load the STL into my CAM package (for you, cut3d) Then generate a toolpath. Towards the end you will see me "POST" code (I dont know what it's called in cut3d, maybe something like generate). The gcode is the text you see at the end, where i load it in a backplot simulator and simulate the machine cutting with the gcode.

I hope this helps the process a bit.

Hi Frenchy,
This one will do simple raster toolpaths.

http://www.mecsoft.com/freemill.shtml

It will be a bit more limited than what you saw in BobCad. The paid version of visual mill can be very powerful, but will cost a bit also. They are partnered with several CAD companies, Like "Alibre" and others.

Ellipse help.

I am trying to draw a ellipse in a rectangle like in a upper post, when I do it, the ellipse makes a full circle and does not stop 1/2 around. I am having no luck figuring out how to do this step. Help is appreciated.

Tony

Hi Tony, yup that is normal when you draw an ellipse that it goes all the way around.

If you only want to keep a part of an Ellipse, you need to cut the ellipse up into pieces - for that draw in a line that divides the ellipse and then use the Edit > Trim tool to cut the ellipse with the line.

See here for some more details about how the Trim command works:
http://moi3d.com/2.0/docs/moi_command_reference4.htm#trim

Let me know if you are still stuck using it - basically all you do is draw in a line that goes through the ellipse, then select your ellipse and run the Trim command, then pick which piece of the ellipse you want to discard.

Thanks. I will try that tonight. I am going to focus tonight on drawing a solid shape and getting it to move to cut3D and practice on their part in this process. Having trouble getting the arc/ellipse (like in the other mans post) to extrude and stay as a solid. Getting the rails to converge as the "tube" goes away is also a stumbling block.

Thanks

Tony
