    Alternative to AutoCADs Dynamic Blocks

    I had started a thread a few years ago, looking for alternatives to AutoCAD, that were able to create Dynamic Blocks. Apparently Autodesk has successfully patented the concept, so in the U.S. there is no true alternative. Though, since we have the rights to our data, I imagine someone should be...

    Entry-point $ for facility scanning ?

    With the cost of laser scanning coming down, I have been researching what the cost entry-point is now for this technology. I came across the Zeb Rivo and Zeb 1 scanners by GeoSLAM. My notes must be messed up, because I have the base scanners, Zeb1 at $2,500 and the Zeb Revo at $$2,360 . But...

    Seeking AutoCAD alternative that can create dynamic blocks

    I originally started this topic in closed thread555-355634 My final conclusion was that GStarCAD was the only non-Autodesk solution, and that still seems to be the case. But I bring the topic up again, in hopes that perhaps one of the 3rd parties have updated their software so that it can...

    Cam follower switch for position sensing?

    I don't have any experience designing this type of cam system, an am wondering if I may be wanting to misuse this type of micro switch. It happens to be a McMaster 7539K5, but I am asking about this general type of switch, rather than this specific model. My application is for a fairly large...

    Good online catalog for pneumatics with search tools and prices?

    I don't normally work with pneumatics, and am frustrated with the sites I am coming across as I search the net for components. Ideally, I would find a vendor with an online catalog that has a good search tool, and includes the technical literature and prices on the components. Currently I am...

    V-belts as adjustable brake/clutch

    I am designing a piece of equipment that will be mounted onto the forks of a forklift. It will pick up a long item horizontally, and either rotate it 180 deg, or take it to a vertical position. What is unusual is that we also want the ability to lift it up, and then let it go to vertical under...

    Looking for a very low cost data aquisition system for distance, air pressure, and temperature.

    A few days ago, I started a thread looking for a low cost distance sensor. [ http://www.eng-tips.com/viewthread.cfm?qid=357437 ] I will now expand on my original query, since I am having difficulty putting an entire system together that is affordable for us. To be specific, I need distance, air...

    Very low cost way to record distance from 1/2" to 5/8" at .01 precision?

    I am setting up a test rig that will need to measure the distance between two plates in a vacuum. The plates will initially be placed at 5/8" apart, and I need at least .01" precision. I need to do this at 5 locations, so cost is a major issue. I really need to keep it under $75 each...

    Shopping for low-cost piping schematic and design software

    I am seeking a low-cost CAD design solution for creating P&ID drawings. In the past, the company has created isometric DWG's using an AutoCAD clone, BricsCAD using basic 2d blocks. Note that this is for medium-sized refrigeration systems (10-20 evaporators, 2 or 2 compressors). I want to...

    Looking for Alternatives to Acad for Dynamic Block creation

    Can anyone recommend a low-cost CAD program that can create AutoCAD compatible dynamic blocks? Alternatively, perhaps an add-on to one of the programs. I have looked at the following; BricsCAD (does not support dynamic block creation, as of the new v14). DraftSight (the word "dynamic block"...
