Newbie needing help making a shape out of a rectangle

[Anonymous]

Hey there, pretty new to this but loving the program. Im trying to articulate a side of an already extruded table leg to a line on an offset plane but cant workout how. I cant seem to sculpt off bodies, only sketches. here is my leg and here is a picture of what im trying to do. I basically want to play around with extruding from a line, to create these geometric triangular shapes out of the extruded rectangle

Any help would be great! Thanks, Will

Hi,

here´s one way to start with:

combined loft and extrude

I used the chamfer tool, is there a better way to do this? as i cant seem to fix the end point of the chamfer to the line i made. So i had to stop the chamer just short of the line, which is not ideal because i cant change the line position and have the chapfers follow.

Hi,

There are numerous solutions for this task.
A chamfer is obvious at first.
But instead, use the Sweep tool and sweep the bevel profile* along an edge. You may also be able to use the plane on the path to help create the sketch with the chamfer profile.

* The profile can also be tapered along the path.

File>Export and then Attach your *.f3d file here.

For a beginner - I would closely replicate the same techniques that you use in the shop to model in Fusion.

Later you can use enhanced CAD tools like Loft that don't really exist in the shop.

I have created a ten minute video just for you. Please note the following:

1. I created the first sketch just for height control of the various segments of the leg.

2. I created offset planes on those height control points.

3. I sketched profiles on those planes as desired.

4. I used a couple of strategic sketches as guides with which to control the size of other sketches.

5. I lofted one segment at a time and combined the results into a single body.

6. I can parametrically control the height of each segment, and the sizes of the driving profiles.

Wow man thank you... I never expected someone to make a video to show me, im touched. Thanks to all the others you replied also

I didn't know you could make construction lines between sketches... It's a deep program and i'm still getting a handle on it, but this gives me another way to look at designing things. I can also see the importance of constraining things 

I'm a recovering SketchUp user so I'm just used to trying to 'extrude' everything into the shape i want. Anyway thanks a lot, Will

This part can be made with simple Extrudes.

One thing I cant work out is how to create this construction line that reaches betwwen the vertical planes attaching the two 'points'. The points seem to desappear when I try to sketch this 'guide rail' or construction line. I even started a new sketch on a vertical plane. not sure what I missed.

Oh it can definitely be made with simple extrudes.

I just thought lofting it would be more entertaining for me while I made the video.

Here it is done with extrudes.

Note: You don't have to put the sketches out away from the body. I just did that for easier viewing in the video.

1. Of course, the order of the sketches is important. The two profiles you want the guide to follow have to exist in the timeline before the guideline sketch. Then the profile sketch that you want to depend on that guideline has to exist after it..

2. In each case, you PROJECT in the existing points you want to use for dependency, then draw to those points.

All of this generally goes much smoother, faster and more efficiently if you - File>Export and then Attach your *.f3d current progress here.

Are your sketches fully defined (black) or are they under-defined (blue)?
