Re: [PEDA] Problem with grid placement of components in P99SE.
Sorry guys, Brain fade, I wasn't looking at the properties window anywhere except for the coordinate locations. I didn't notice that the properties window was defaulting to the reference designator tab and giving me the coordinates of the reference designator rather than the component. All the designators are centered and thus have some weird coordinates. Sincerely, Brad Velander, PCB Designer. Northern Airborne Technology 1925 Kirschner Road, Kelowna, BC, V1Y 4N7.

[PEDA] Problem with grid placement of components in P99SE.
Hi guys, new job, new designs, new libraries, a whole lot of unknowns to me and I am getting a problem that I have never previously seen in Protel. Placing components using a 5 mil grid, check component afterwards and it is not on that 5 mil grid. There is a funny little grid variation by 0.001mils on every part in this database but there are also some parts off of 5 mil grids by a fair distance after placement. Yes I am using the Options "Snap to Center" checked. Real example: Using the 5 mil component placement grid I place a component at coordinates 6200mil, 0mil. After placement I check the component properties and it reports that the part is placed at coordinates 6146.501mil, -14.499mil. As a first step while I am waiting for any replies, I am going to ascii out the database and ascii it back in, just to try and see if that fixes anything. Sincerely, Brad Velander, PCB Designer.

Re: [PEDA] 3D Models Online
Hey Jason, See my answers to your questions below. Q1: Is it worth doing? I've thought about the benefits of this previously. In my case however, I don't think it would be worth it. Having dealt with alot of offshore suppliers etc., we try to hedge our bets so to speak. We've been burned a few times when a plastics shooting company doesn't give the necessary clearances around components etc. As a result, when I model 3d components I generally model them as MMC + 0.4mm per side and MMC + 0.2mm height. This ensures that we get at least a minimal amount of clearance. Another issue (which could be overcome) is the level of detail of a part. For instance, I downloaded a model from Molex for their ZIF flex socket (51374) that has every feature modelled to the point where it can be opened and closed. For my purposes, this is far more detail than necessary and only slows down my CAD system. I only need the basic outer dimensions and enough detail for any mating parts (in the case of connectors etc.) It would also be far more beneficial to have the models in native CAD format rather than a generic format like .stp or .igs so that features can easily be removed or added. I typically like to set up my models so that they can be placed manually or used in an IDF conversion program. Therefore, I build them using the same reference locations as used for the part footprints in Protel. Q2: What do you think is a good price for a model of the following? I'll pass on this question for lack of experience. Q3: Would you use the service? Though I think it would be a beneficial service for some, I would prefer to keep our 3d modelling under my own control due to the uniqueness of the issues we face. However, I can see certain situations (such as a time crunch) where being able to download the model would be useful. I think the need for this service would increase if the Protel -> 3d (IDF) conversions worked better (I've trialed IDF modeller, and use Qualecad, but only for Protel 99SE). Hope that helps, Darcy Davis Design Engineer, Dynastream Innovations, Inc. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
[PEDA] 3D Models Online
Hi, I'm thinking of setting up an online 3D model development bureaux. Do the forum think this is a good idea? If you have time, please answer the three questions at the end of the email, or feel free to comment on the idea. The service would concentrate on 3D modelling for electronic product design, that is; PCB components, complete PCB assemblies and product enclosures. The customer would apply for the model on-line. If they have any specifications that they want to apply, they could attach these to the order. If it exists in the library, they could pay a small nominal fee and download it, it would then be theirs to do what they want with. Obviously if the intellectual property was owned, then they could not re-sell it. If it does not exist in the library, then they could pay for its creation, the price would depend on the complexity. The library would accept submissions from others, if their model was then later sold, the original sender would benefit from it. The library would also house license free models, free for download if that model can be verified as being not somebody else's property. I would offer other services, such as model conversion, visualisation modelling and CAD drafting services, these would be priced per job. Q1: Is it worth doing? Q2: What do you think is a good price for a model of the following? A simple PCB component, such as a capacitor. A more complicated PCB component, such as a transformer. A PCB component with more parts, such as a connector. A simple enclosure, e.g. a square box A more complicated enclosure, e.g. A desktop case An even more complicated enclosure, e.g. rack mount Q3: Would you use the service?
