how to make a dxf imported file usable

max_malossini

I converted an image into a dxf file (the silouette of a truck) and imported in Onshape. The doc available below. WHen I open the sketch, all the lines are actually made of many shorter segments.

My goal is to 3d print this as a flat keychain-type model, in multicolor (it's a surprise for my son's "new" 1989 f150). I looked up how to merge multiple segments into one line but I can't make sense of the solutions that I found, none of them seem to work. I'm relatively new to Onshape, so maybe I'm not thinking of the right way to approach this.

Any help/suggestion appreciated

@max_malossini Yes, I selected the "gaps" to extrude to one depth and all the panels in another extrude to a different depth. Yes there is a zero gap between the panels and the gaps, so it would print as one part.

You are going to need something to connect the tires to the body if you want to print as one part.

There are a few different ways to do this, but here is one way:
When inserting a traced dxf, you can (while within the sketch) Sketch Transform scale the initial sketch way down and it will fill in the "open" contours, allowing you to select them for the Extrude feature. You can then use the Feature Transform feature to scale the part to whatever size you need.

Hi Max,

Not sure exactly what you're after, but the sketch loops extrude just fine for me.

Thank you to both, though I am clearly missing something.

smurfcad: I will try to extrude all at once, without "add" new parts and try to print it at least in one color. if I were to export what you have on your screenshot, would it print the blue parts including the gaps? did you extrude both ligaps and body with different depths?

MPascoe: I did transform and made it smaller and moved away from the original sketch but then once I close the sketch it disappears.

To make things more complicated, I also added a new sketch for the truck shell, and even though I selected all border lines and points on the new windows etc. and set "coincident" all, I still don't see shadeable regions to be extruded.

I definitely need to watch more tutorials, I don't even understand what to ask for :)
