We will be able to use some of what you have already done, but for the foundation I want to start from scratch.
Start a new part file and create the sketch as shown.
(Note the 3° and the 91°.)
If you want to change these - change them now.
Save the file as Bike Frame Master.ipt
I went ahead and completed some of it - notice use of multiple solids (expand Solids Bodies folder at top of browers and turn off visibility showing only one at a time.
Notice use of Sketch Block that I can test kimematics (drag sketch 5) (I would actually do the entire master as sketch blocks before creating any solid geometry - but I thought that might get a little confusing).
Ffor the puposes of this instructional, do you need me to stick to the measurements you are using in your creations? Will it mess things up if I use the measurements from the mule?
change to your dimensions - you left most everything undimensioned - so I was making things up along the way.
What I couldn't figure out - a lot of stuff I dimensioned on yours was perfect size, but no dimensions? You must have erased the dimensions. Why? Are you aware that you can simply double click on dimensions to change? Are you aware that you can hide dimensions if the become obtrusive? No need to delete - just creating extra work (and danger of making unitended edits) if you delete them.
I've been trying to keep the workspace tidy by keeping only the things I actually want present, hiding them or turning them off may very well be the better way of doing
Well, this eve I've created an accuratly dimensioned sketch and begun to extrude the lines into tubes using a workplace at the line nodes. I'm a bit stuck because Sketch 1 has been consumed by an extrude, and I don't seem to be able to share it to extrude the final parts.
Sorry if it's taken a while to post up this stage, the free time I have to learn a CAD is sparse.
This is where I've gotten up to recently, I only have one body made from many extrudes, and the sketch for the main link (labelled). It won't extrude because of a self intersecting loop, which I can't see from looking at it. What will be the next step?
Edit your sketch block and zoom in here (see image) with Constraint visibility On.
You need to use
you need to use
you need to use constraints, constraints, geometry constraints. (you are missing a bunch of tangents).
I recommend you put this project aside for a day or two and go through these -
it will save you time and frustration.
Did I mention using geometry constraints?
Once you learn the sketcher - most of this work is done for you automatically by Inventor.
