I am working with a drawing provided to me by someone else, and where there should be arcs they have multiple line segments. I need a radius for what I'm doing, so I drew a circle with TTR and then tried to trim against the tangent lines to get my arc. However, sometimes this works and sometimes it doesn't. why this doesn't always work?
View 5 RepliesI drawning 2 circle as radius 250mm.the distance between two circle is 0.08mm I drawing one line segment between two circle and I Expanding line segment as length 20mm.then I offset this line The amount 2.5 mm in vertical side up.
When I trim these horizontal line that are Cross-Being with two circle the Remaining line segment is shorter than real distance between two arcs I thinks its happening?
Also I attached 7 pics I try show my problem.
Also when I want obtain horizontal distance with distance command or by linear the intersection is not start from circumference.
whats this and how I can get real horizontal distance between two arcs
I want to find the tangent intersection point between 2 circles within certain conditions.
Circle 1 is r: 30 m and is fixed.
Circle 2 is r: 20 m and its position is inside circle 1.
Circle 2 can be moved in a given angle.
The question is: what distance should circle 2 move, to become tangent with circle 1.
change all circles of a certain diameter in a .dxf file to points. I received the following lisp file. For the last 10-12 years it has worked great. We create many custom sized parts that could be cut on a plasma (utilizing the circles for holes) or punched, assigning a crosshair tool to the point. Now we are switching to a laser, and want to etch a crosshair at this same location. Our solution has been to draw the crosshair and copy to each required location. Sometimes this may be 20 to 30 locations. Now I would like to know if there is a way to replace all of these circles with a crosshair. This could be a similar lisp file, or an easier manual operation. I know that I can select all of the circles using the filter command and specifying the radius. But I don't know how to assign the 'crosshair' to these locations. (defun c:ctopt ( / ename cnt ss) (setq ss (ssget "x" '((0 . "CIRCLE")))) (if ss (progn (setq cnt 0) (repeat (sslength ss) (setq ename (ssname ss cnt)) (if (equal (cdr (assoc 40 (entget ename))) 0.025 0.005) ;use this line for a radius 0.025 +/- 0.00015 ;(<= (cdr (assoc 40 (entget ename))) 0.05) ;use this line for a radius of 0.05 or less (progn (entmake (list '(0 . "POINT") (assoc 10 (entget ename))(assoc 8 (entget ename)))) (entdel ename) )) (setq cnt (1+ cnt)) ) ) ) (princ) )

I am trying to create an arc between two intersecting circles whose start and end points are at x and y dimensions on the two circles and whose arc is defined by the tangents of the two intersecting circles.
I draw a circle and then want another smaller circle to snap to the path. This would produce 100% accurate smooth curve.
I added a line that snapped to an anchor point I added on the large circle. I was hoping to snap the smaller circle to the anchor point, but how can you do this without guessing where to add anchor points on the circle? What if I want to change them?
Right now I have snap to point on and snap to grid off. Align to pixel grid is also off.
method for drawing and conecting tangents?
In my drawing, of either a part or an assembly, how do I display tangent lines?

I used Solid Edge for my entire professional career. One thing that is driving me batty is how, when necessary in a view for clarity, tangent lines are displayed and how to change them, or at the very least, come up with a work around to display them how is needed. In general, tangent lines are first, supposed to be of thinner lineweight, but also, are not supposed to extend all the way across the surface of a part, they are to leave a small gap.
I have found and tried the option of displaying tangent lines, and also have checked the for shorten option. The issue is, in many of the parts the gap produced in HUGE. So I've spent a few hours tinkering, and I finally decided to try and define a new linetype using autocad express tools. So I tried this, but to my dismay I haven't been able to set up a linetype that only has a gap at the end. See attached jpeg for illustration.
In other softwares when you creat a spline you are able to adjust the curvature between points by dragging the slope handles at a node. In my file, I have thus far been unable to fair my splines with any kind of consistancy. Also, it should be possible to place a tangent constaint to a straight line at a point, yet I haven't been able to do that either. According to the help files this should be an easy thing to adjust, Why am I not able to?

View 2 Replies View RelatedIm having a little issue with connecting lines and circles but not sure how to shorten the question to do a search on here. I have 2 concentric circles (the two circles form the walls of a round tower wall) which have 2 lines (representing a wall) passing through them. I want to join the circles from the circumference to the lines, but each time I try to do it the line seems to default to the center of the circles and to the endpoints of the lines which is not what I want. The eventual aim will be to remove a section of the circles and the lines where the new line connects to them to form an opening in the walls.
Ive tried <shift>right click and selecting tangent on the circles but I cant figure out what to do on the lines and it constantly defaults to the end of the line not to where I want to intersect the lines.
Like when I draw a cylinder, instead of a solid cylinder I get two circles joined by two lines. How do I change this so that I get the solid?
View 3 Replies View RelatedI am not able to draws circles and lines etc. using the ribbon or the command line. i am using the correct procedures per the tutorials and I have Google search how to add circles. I click the circle on the ribbon, choose my center point and drag to choose the radius, left click and no circle, same procedure for a simple line.
Is there something that needs to be activated for these to work? I have an activation code which I do not remember using when I installed the software, I only remember using the serial number and product key.

View 4 Replies View RelatedI am trying to make a hexagonal lattice of circles (1 micron dia, period - 3 microns) and exted it over a square cm in area atleast. The final objective is to make this as a mask pattern for the Laser fabrication/writer. So I create the pattern over a small area and use array command to extend it over a finite area (~500 microns or so). I then combine these points to a single block and then use the mirror command to extend it even further. But as soon as I reach an area of 2.5 mm square, the program seems to slow down and doesnt respond. I assume this is the limitation of my computing power to handle so many objects at once. (I have 4 GB RAM and 97 % is utilized at this time). Is there a way to circumvent this computing limitation, making use of some facility/command within AutoCAD?

View 9 Replies View RelatedI am trying to create a circle with a pre-defined diamter of 7mm, and then I want to add 20 (twenty) generated lines intersecting another 20 lines across the circle.
TO make it more difficult, I need to pre-define the width of the lines, as well as the spacing of the lines.
How do you smooth lines? Like if I trace something and the lines are just a touch jagged, how do I get them to look perfect? I'm using PS7.
Also, how could I make concentric circles? Or even just a hollow circle? I can use the shape tool to make a circle, but that fills it - is there a way to make it with just a 2 or 3 pixel outline and hollow in the middle?
When I drag out a circle, or use the node to curve the corners of a rectangle, the line isn't smooth. It looks like it's slightly jagged.

I'm trying to create dotted lines that are actually circles and not square shaped dots (the given option in the outline menu). Is the best/only way to do this by creating a new Artistic Media Brush?

View 14 Replies View RelatedOkay, I'm new to associative arrays, I'm attaching a drawing so you can see what I'm trying to accomplish with this. I'm doing an elevation view of a slab that has a cross section of the rebar. I've shown one of the bars spanning from left to right, represented by a rectangle, and the cross section of the bars running front to back represented by circles. You can see what I'm trying to show here. In the drawing I've attached, the top three sketches are examples of how this would look if it were working correctly.
What I'm trying to do is create an array (of circles) that will stretch to the length of the bar spanning left to right. I want the quantity of items in the array to automatically change based on the length of the bar and the spacing of items, so if there is 6" of spacing between the items instead of 12" it will automatically add twice the amount of items to fill in that space. I've been trying to use a path array, and it isn't working the way I want. I'm not familiar with rectangular arrays, so not sure what to do there either.
