equal sketch

equal sketch

equal sketch

(OP)
Is there such a thing as an equal sketch?  Basically I have 2 sketches (that I will extrude) perpendicular to each other, so I can't convert entities of one to the other, I need to recreate it (as far as I know).  Is there a way I can say this sketch is dimenionaly and geometrically the same as the other just oriented different? I need to mirror one of the extrudes not the other so a sweep wouldn't work.

Also this is a one time thing so a library feature wouldn't make sense.

Maybe there is another feature I can use as opposed to extrude.

RE: equal sketch

Edit first sketch, select all, copy (ctrl-C), open the second sketch and paste (ctrl-V). Good luck!

RE: equal sketch

(OP)
Dan, thanks.  I think that will work most of the time when I need to do something like this.  Just messing around with the derived sketch command I saw you can't rotate the sketch, I can see that being a problem.

SerGhi, I tried copy and paste but I would still have to have dims.  I would like to not have dimensions basically it would just reference the original sketch.

Thanks

RE: equal sketch

Once you place the derived sketch on the face of your choosing you can constrain it however you like.

RE: equal sketch

You can copy anything you want (including dims or just part of dims or you can delete dims on the second sketch) and they are not referenced, just if you make constrains on them.

RE: equal sketch

grunt58,

   In your sketch, right click on the dimensions, then link them.  I find this a very useful feature.

RE: equal sketch

grunt58,

You can also just copy the feature and paste it on the appropriate face.  You'll be prompted to deal with the dangling items (delete or leave dangling - I leave them dangling then edit the sketch to fix the dang dangles).  This is a lot faster since it gets everything in the sketch AND the feature it was made into.

Might it also be possible to make a circular pattern of this feature?  This is even better if it gives you what you want.

RE: equal sketch

(OP)
SerGHi I want references.  I want a fully contrained sketch that i just need to position.  Similar to using a library feature.

Dan, constrain yes.  Rotate was greyed out along with all my other sketch icons.

Linking would work and it is useful but more steps then I think is needed for what I was doing.

Circ pattern wouldn't have worked different extrude lengths. Though, to be honest I didn't even think of it.

RE: equal sketch

Make a block.

RE: equal sketch

(OP)
block would be no different then a library feature.  This is a one time part.

I see it like this I already drew  & contrained the sketch.  I should be able to copy it and paste it "as a block".  The only thing I need to do is orient it and dim it's location.  Basically creat a block inside the part.

RE: equal sketch

Can you revolve the sketch into a surface and then use the edge of the surface instead of creating a new sketch?  I hope this helps.

RE: equal sketch

The sketch or feature could have been copied or redrawn and linked hundreds of times during the duration of this thread.

 

RE: equal sketch

(OP)
Agreed I've been done with this for half a day.  I think Dan's suggestion on a derived sketch will work the best for my needs.

I still think being able to make a block of a sketch and keep it inside a part would be useful.

Thanks all.

RE: equal sketch

Show the older sketch while editing the new sketch. Select one line at a time and its counterpart on the older sketch, select 'equal'.

RE: equal sketch

I think the following will work.

Create a plane 45 degrees off from the other two.  Create a sketch on this plane and use convert entities to project the original sketch onto this one.  Then use convert entities to project the intermediate sketch onto the second plane.  Attached is an example in 2008.

RE: equal sketch

A block is very different from a library feature.  The definition of the block can be defined and stored within the model file, without need of external files.

RE: equal sketch

When you insert a derived sketch click and drag a vertex to move the sketch away from what it's derived from. Then to rotate fix one of the points and drag another vertex to position at an angle. In SolidWorks sketches lines can only be moved in a direction normal to itself. A vertex lets you move in x and y directions but won't rotate attached lines. Also look at the Move/Copy flyout icon or Right Click to access if you want rotation of the sketch. Another thing that comes in handy is sketching an angled line and using Parallel Perpendicular instead of Horizontal Vertical.

I typically move the sketch as described above and place one coincident constraint and then a parallel to place it along the original. The nice thing about Derived sketch is it can be used to place identical cuts several places on a model and change all the sketches at once by modifying the original. The drawback is you cannot individually change entities from construction to solid or add additional geometry. The drawback to this is that you need to make sure you have all the references for placement in the original sketch.

Linked dimensions are one of the greatest things in SolidWorks and I recommend using them If you are making a bunch of circular holes of differing diameters you can modify any of the diameters in any feature and up date the linked group. Derived sketches work better with complicated sketches because instead of linking all the dimensions you Derive the entire sketch.

Blocks will give you a lot of benefit because you can edit the block from any of the sketches that use it and add additional construction or solid entities.

Tick, didn't know one could store it in the model file thought they were stored externally.  I will look into that.

I drew a similar part different dims, later in the day and used derived sketchs and it helped speed up the process.  Rotating etc was not an issue when SW created the derived sketch it always had it in the right orientation.

This thread shows in CAD there many ways to accomplish something as easy as making a sketch.
