Trouble using image clip to crop curved lines, arcs,circles

[Anonymous]

Hi There

I hope someone have had the same problem as myself.

I need to take a floor panel with curved lines and radi but can not use Image clip because the curved is not classed as a closed polyline.

does any one know how I can crop an image with image clip without having to trace the curved line with many small polylines.

The help is urgent and will be greatly appreciated.

ARC command? the join to a Pline.

Or PLINE command has a "curve" option and can be part of your "closed polyline" requirement. Read these

and

There is no automagical tracing tools in LT: if you need tracing ability, you need to subscribe to full AutoCAD with the Raster Design subscription as well. Contact a reseller in your region of the world and ask for a demo on your own files.

To add you can use the trial version of full AutoCAD 2017 here: http://www.autodesk.com/products/autocad/free-trial 

If you are in a time crunch this could be a temporary work around.

Circling back on your thread, did any of the posts in the thread help with you issue?

Please post back in the thread if you are still having an issue with AutoCAD.

This solution absolutely does not work. I tried it out and still only got crops along straight lines. Regardless if you use a PLINE or ARC commands and join the arcs together to form a PLINE, the boundaries will always be set by the straight segments between the endpoints of each arc. So the only way to make this work using the method described above is to use lots of tiny arc segments or PLINES to create lots of endpoints that can be recognized as boundary points. Technically it's doable but looks really ugly and takes forever. As a student it's sad to know there just aren't any free programs out there that can crop along curved lines and be dropped into AutoCAD. I can't afford the full version of AutoCAD so that's not an option either.

@Anonymous Students get Autodesk software for free, if they are legit students attending legit educational facilities. If you are paying for EDU software, you are being taken advantage of and someone is stealing your money.

@pendean  I have the EDU version for free, no one is taking my money and no one implied so. I don't know if the full version (aka non student version) can solve this problem this way, but that is besides the point. The point is your solution does not work. Instead you can use Pixlr (free online Photoshop alternative) to solve this problem with the magic layer overlap tool. Just use the tool which can solve this problem in 2 clicks instead of going through the entire process you recommended. I hope this helps anyone else with a similar problem.

So you lied, I mean ranted for no reason at all, plus you waited until someone responded (me) before offering up a fix. Interesting approach to sharing information LOL

Happy Cadding.

Dear pendean,

Sometimes finding a fix takes time. By the time I found a fix (for students who have the student version and not the complete version which costs a lot of money) you had already responded, offering no positive contributions or alternative solutions to this problem. It is obvious you are intent on arguing instead of addressing this problem, as is evident in your last response. I would rather focus on solving this issue.

To any users encountering this same problem, I invite you to try the Pixlr solution I mentioned in my comment above, as it is a program created in similar fashion to AutoCAD with a UI similar to Photoshop. One thing I forgot to include in my solution above is that Pixlr requires a .jpeg or .png file, so you can use any free PDF to JPEG converting website to change the format of your image, then upload the image onto www.pixlr.com to edit and overlap the image from there. The editing software is easy to use, completely free and online, so you don't have to download anything. I hope this helps, good luck.

This is the easiest workaround I have used. Let's say you want to use a circle for the imageclip limits.

-Copy the circle off to the side

-Turn off all osnaps except for nearest

-Using the polyline command, trace over the circle using the nearest snap. Be sure to close the polyline with an endpoint snap.

-This will result in a closed polyline that looks like a circle. You can now use this as your imageclip limits.

The same workaround will apply for arcs, etc.

You could also try the command CLIPIT. You select the polyline with curves first, then the object to be clipped and then give an accuracy figure and it will clip around the curves to this.

[pendean]

@elaineF7BKN There is no CLIPIT command in LT (the topic of this forum) or as a core command in AutoCAD: do you mean something else? Or is this a LISP (not an option in LT, the topic of this forum)?
