klrskies Posted May 3, 2011 Share Posted May 3, 2011 I'd like to place a point at a specific "Z" level on a line. The line is not perpendicular to the x~y plane. On the attached .dwg, say @ z+.750 on one of the angled lines on the "constraints" layer. 0699 Cadtutuor.dwg Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 3, 2011 Share Posted May 3, 2011 Draw a line going up on Z axis, say (0,0,0) to (0,0,.75) Then use commands ucs za o and select the end of the line. Now you ucs is at .75 and you should be able to figure it out from there. There is another method that slips my mind at the moment (elevation or something like that). Change view, apparent intersection, that sort of thing. (I just did it so you should be able to figure it out.) Quote Link to comment Share on other sites More sharing options...
ReMark Posted May 3, 2011 Share Posted May 3, 2011 Could the task be accomplished using Point Filters? Just curious. No, I don't know the answer. Quote Link to comment Share on other sites More sharing options...
eldon Posted May 3, 2011 Share Posted May 3, 2011 If you consider the lines that are on the Constraints layer, they either have Z values that are 0 one end and 1.5 the other end, or are 0.75 at one end and 1.5 at the other end. If you put a point at the mid point of the longer lines, it will be at z + 0.75 Quote Link to comment Share on other sites More sharing options...

eldon Posted May 3, 2011 Share Posted May 3, 2011 Well it did for this example. But for other times I would try and work out what JD Mather was suggesting. Quote Link to comment Share on other sites More sharing options...
klrskies Posted May 3, 2011 Author Share Posted May 3, 2011 Haven't tried it , but moving the ucs to a specific z level causes an attachment to occure to a non-perpendicular enity at that level, that isn't a snap point? seems there were would be an easier way, but I don't know...

Yes, and thats what I'm doing for this instance, (saw that after the post was started) useing the midpoint, but I'd like to know how to do it if it doesn't fall on an available snap position.

klrskies Posted May 3, 2011 Author Share Posted May 3, 2011 Elevation .75 apparent intersection I'll try that. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 3, 2011 Share Posted May 3, 2011 I'll try that. Would you like to hear how much easier this is in a modern 3D CAD program like Autodesk Inventor? Quote Link to comment Share on other sites More sharing options...
klrskies Posted May 3, 2011 Author Share Posted May 3, 2011 Would you like to hear how much easier this is in a modern 3D CAD program like Autodesk Inventor? Yes please. I have mechanical 2008 &2010 available, so I'm intrested! Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 3, 2011 Share Posted May 3, 2011 Yes please. I have mechanical 2008 &2010 available, so I'm intrested! AutoCAD Mechanical is not Autodesk Inventor. Quote Link to comment Share on other sites More sharing options...
klrskies Posted May 3, 2011 Author Share Posted May 3, 2011 Yes, Does mechanical not have features that would help me as much as inventor? I can get a seat of Inventor too. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 3, 2011 Share Posted May 3, 2011 (edited) AutoCAD mechanical is a 2D drafting program (that is built on top of AutoCAD and therefore has AutoCAD's 3D tools). Autodesk Inventor is a completely different next-generation MCAD software. Well I tried to attach a small video here on how to do it in AutoCAD, but the attachment size here is so limiting. 1.Set elevation to .75 2. Draw horizontal line across screen. 3. Go to back view. 4. Point apparent intersection pick angled line first then horizontal line Pictures didn't show in exact order. Start bottom left (after setting elevation) then go counter-clockwise.

klrskies Posted May 3, 2011 Author Share Posted May 3, 2011 (edited) Whats "MCAD"? Please tell me / show me more regarding inventor. Edited May 3, 2011 by klrskies Quote Link to comment Share on other sites More sharing options...
eldon Posted May 3, 2011 Share Posted May 3, 2011 I don't know how you are getting on, but here is a way of constructing a line which gives you what you want. It uses the .XY filter which is a way of getting the XY coordinate from something already in the drawing, and giving a Z of your choice. It works in the view of the posted drawing. Consider Constraint line AB. Draw a line from the .XY of the Endpoint at A and give it a Z of 0.75 (point A1), to the .XY of the Endpoint of B and also giving it a Z of 0.75 (point B1). This new line intersects the original line at C which is a true Intersection at a Z of 0.75. Quote Link to comment Share on other sites More sharing options...

JD Mather Posted May 3, 2011 Share Posted May 3, 2011 Whats "MCAD"? MCAD = Mechanical CAD (a generic term - not to be confused with AutoCAD Mechanical) Examples: Autodesk Inventor, SolidWorks, SolidEdge, Pro/E (Creo) AutoCAD is a general purpose computer aided design program that is not optimized for anything. There are several 2D and 3D vertical applications (like AutoCAD Mechanical) that are built on top of vanilla AutoCAD to try to address certain fields (Electrical, Civil, Architectural...). But the next-generation field specific applications seem to be moving away from AutoCAD base to clean-slate "how would we do it today given 25+ years of CAD experience" paradigm. (Revit and Inventor are two examples.) If you are young (or even not so young) and preparing for the future I would be learning one of the next-generation tools. Otherwise you will be competing with a huge number of existing AutoCAD users for employment. And in my opinion the new tools are just plain fun compared to AutoCAD. Do you want to work for the rest of your career or "work as play"?
