Slow with selecting and moving objects.

    Hi Richard.

    It has been mentioned by others that the 64 bit program could perform faster.

    I moved up from ver 2.0 ( 32 bit) to ver 4.0 (64 bit) and bought a high spec Lenovo w/s ( err , well it was 2014) with a E5-1660 V2 64Gb 1866 Hz ram Nvidia K4000 - thought it was going to rock...sadly not though.

    So i do this, it may help you - forgive me if you are an experienced user and know this already.

    1. Spline surfaces are very data dense, work at the lowest graphical setting ( that's visually acceptable to you) for these surfaces / bodies. Selecting a body allows for individual body graphical setting under options. It can be altered at any stage in it's properties. Once done, why not turn it down to level 3. Although settings allow 1 to 10, 5 is usually fine in what i do. Turn up spline surface parts to level 10, add some fillets etc and let the wait begin...Geometry accuracy isn't affected by graphical setting.

    2. In options, i turned  'Power Selection' off - this has really helped. I also had  'All Bodies' ticked, so the auto selection was also searching all over the file at times - causing massive slowing and occasionally 'hang ups' but now, not anymore. In selecting common faces of two or more bodies, the selection enquiry search will then apply to their respective bodies or 'all bodies' if ticked - thus allowing power selection but as an intended action and not the will of the program.

    3. I put body's into 'components' - and i use assembly hierarchy approach to structure the design.

    4. If files are getting 'heavy' - i think it's possible to 'open' that particular component, save it and import it back - this is a sure way to lighten the assembly file - it also allows the saving of 'components' as versions - i'm doing this more and more as i gain experience. I would advise you to try this.

    In general i have to agree with you. i expected more grunt - alot more ! I find it difficult to explain why DSM 'feels' apparently 'weak' and yet Spaceclaim 'appears' very muscular especially with thousands of holes in sheet metal demonstrations. Put a couple of hundred holes down, especially with power select turned on, add some chamfers / rounds and then the waiting really begins - that's why i turned off 'Power Select' and never regreted it.

    Realistically though, in decades of designing, the times a single part has had more that 50 holes - i can't remember!

    Final comments...

    Working as above, i get it done, sure i'd like quicker results but 95%+ of everything i do, DSM snaps to it very admirably - if i get odd numbers occasionally, that's me not DSM.

    Probably the Sheetmetal app in Spaceclaim has unique accelerators.

    A power program such as Creo Parametric v7 just released announces the ability to set an absolute accuracy of 0.0001mm and not a relative accuracy. As far as i know, DSM works to an accuracy of 0.00000001mm ( 4 orders of magnitude greater ) all the time - thus calculations on complex data sets take more time.

    It might be possible to alter a particular 'part accuracy' and increase the speed of operating on it - i have no knowledge how to do this - does anyone else reading this?

    Hope my comments have helped in some way...please reply if these tips help or not...
