i imported a complex dxf, is there a way to lock the sketch down and fully constrain it without dimensioning everything
You can use fully define sketch tool and let it take care of the sketch.
thanks Deepak...I tried that but the sketch is complicated and I believe it did not work....is there a way to fix the sketch or lock it down prior to making changes? thanks
Select everything in the sketch and apply a Fixed relation
Not totally sure of the application, but did you try to make a block. Tools, Blocks, Make.
I did try to make a block, however I want to add tangent fillets to areas and I don't want other part of the sketch moving on me
I imported this dxf and I want to add 1/16" radius for tooling bit but when I do that everything is moving on me
I'd think that Jim's suggestion would work best. Select everything and set the "Fixed" constraint. Then it should still let you add radii between fixed segments but won't move anything.
Or make another sketch, convert entities of everything in the first sketch (which basically makes a new sketch fixed to the original) and then add your fillets to this second sketch.
when I select everything the "Fixed" command is not available? Thanks in advance
I'm inclined to agree with Chris' second suggestion. I've done a fair bit of "import DXF and clean up for manufacture" stuff and that's most likely the approach I would take. It leaves the original unaltered for reference and as long as you don't edit the sketch it should remain unchanged regardless of what happens in your copy. If you can post your file,(click on "Use advanced editor" in the upper right corner to attach files) someone may be able to figure out why Fully Define SKetch and Fixed aren't working for you.
If there are too many entities in the selection then for some reason the fixed command is not shown right away. Instead you are presented with a selection count and a button that says "Show Selection". Don't ask me why. But all you have to do is click on "Show Selection" and then the "Fix" button will be there.
You may have hit on the reason that Fully Define Sketch and Fixed don't seem to be working for Jesse. A complex sketch with lots of entities can take longer for SW to sort out than people are used to waiting these days.
I've seen Show Selection before, it's as if SW is saying "Are you kidding? They're gazillions of those things, what could you possibly do with them all? Are you sure you want to see them?"
I once say some one in a sketch draw a rectangle then draw a diagonal line through the rectangle from corner to corner and then make the diagonal line and origin a mid-point. For a long time I didn't see the point, after a while I realized that this mid-point was always constraining the sketch. Most of you sketches start with a rectangle. Adding this focal point keeps the model centered on the sketch plane and locks the first sketch into place, of which all other sketch usually start from. This by no means is a fix all but it does make sense to lock in the first a primary sketch to the origin.
sorry for the delay been busy at work. I found the command yesterday as Jamil pointed out. I appreciate all of your support and timely replies. Thanks again.
