Drawing lines onto geometry

[martinkindl83]

Hello guys.

Im designing balsa RC planes for laser cutting. I was using Sketchup before and im trying to switch to Fusion360.

One of the problems i discovered is drawing lines onto existing geometry.

Something like in this image. Im finding Fusion360 very hard for my designs, as i usually dont have exact measurements, until i start putting components together and aligning them. At that point i have to do and move/push/pull faces on components to get correct placement and pieces lock together like big puzzle.

Draw lines in sketches,

or create planes with the Construct menu.

Might help...

Creating 4 extra sketch planes for simple line doesnt seems very fast
approach 😞

While what @davebYYPCU is going to accomplish exactly what your asking, my guess would be that you want to cut that corner off ?

But regardless of what you want to do in this particular case, you will likely have to re-think your workflow. Designing in a parametric CAD software such as Fusion 360 works quite differently and likely requires changing your Sketchup based workflow.

If you ask too narrow questions, then the answers you'll receive will only support a workflow that already is suboptimal for achieving your goal with Fusion 360.

Yes, i was afraid of that.

Problem Im facing is that in parametric workflow you usually have dimensions to start with.

But in my case i have rough shapes, that i have to put together and assemble, then im creating some extra notches as locks to help with building.

so the work flow is to create rough shape, create notches and then when its done go and polish dimensions (2.59682mm to 2.5, etc), but at the time of sketch i dont have those "notches"

At image i circled those notches and marked dimensions that likely to by changed once assembled.

While you might have some rough overall dimensions you most certainly don't have all fo the dimensions, because if you did , what would there be to design ? 

It is fairly common to adjust one's workflow to suit the tools and overall concept of a CAD software or really any software tool. I'd never atmpt to model the same way in Blender and Fusion 360 and even 2 of my main CAD systems ZW3D and Fusion 360 work similar but also very differently.

Thank you Peter.

I will play with it little bit more and maybe i will come up with some other workflow that would suit this scenario better.

Change your thinking, Building outside in, workflow works for me.

You need the plan or sketch (Canvass)

Draw the top and side views, (Master Sketches)

make the fuse hollow, (Patch Loft and thicken)

add stringers, (Sweep)

 

cut the fuse into sections, (Sketch planes) and make the former sketch nearly last, with the Command 

Project > Intersect > Body.  works the same for flat sides too.

Half former sketch is given to you, with new sketch on the plane where you need it, by a click on each of the four white bodies in the list.  No mental gymnastics required.

Here are two methods shown how to do what you want.
