import the photo. right click on it, explode it. now it’s a face with a texture. now using the various line and arcs tools, draw the contour of your element. and delete the extra bits. like using a pair of scissors. then you can pushpull the middle face.
Got it, my apologies about the profile. I believe I have corrected that.
One final (i hope) question. The Sketchplus polygon lasso tool would be perfect for this, but it askes for my license which after checking all my emails, I never received and can’t find within my plan. Can you advise me on where to find it?
Thanks very much and sorry to keep bothering you!.
Sketchplus is a licensed extension. The Extension Warehouse page for it says you must obtain a license from the author’s website, separate from your SketchUp license. If you did that and received no reply you should contact the author.
It would help if you’d share the image you are trying to get the 3D model from. It might be that the extension I mentioned will do the trick for you quickly and easily or it might even be that tracing the image isn’t the best option.
Here’s a quick example with a low res image I dug up.
For things like those I wouldn’t even bother trying to trace or otherwise work directly from the images. For the De-Sta-Co-Style toggle clamp you might find something useful in the 3D Warehouse or you could get dimensioned drawings from the manufacturer or from somewhere like McMaster-Carr. I have a vague recollection of modeling a clamp similar to that some years ago.
The other one would be simpler to model from a few basic dimensions which you can get from Amazon or Rockler if you don’t already have the clamp in hand.
You might give some thought also to modeling only the important details of these things. The screw threads, for example are probably not important. The exact shape of the handles are probably not critical either. Simple representations will go a long way toward giving the information you really need for your project.
I use a app called Snagit from techsmith,
you can use a fill tool to fill a transparency, basically changes any selection or matched color with transparency. Just fill you white background and your done.
Works perfectly, and can save to any number of file types
