Importing, scaling, dimensionning issues

having a couple of issues getting to grips with maya(version 5). am using the prgram (or hoping to) for architectural rendering and/or modelling. any help greatly appreciated

a) should you model at 1:1 in maya? do 'large' objects affect processing speeds or is it just the detail? if working at a real scale can you increase the size of the grid (not just change the grid spacing)?

when importing dxf's they seem to come in huge. is there a quick scaling solution as i cant seem to scroll out far enough before they just disappear?... do dxf's come in with the dimensions they were drawn at or does maya scale them?

c) when scaling or duplicating can i increase an object by dimension not percentage scale? (e.g scale an object to be 'x' units larger in every direction instead of working out the percentage increae needed to achieve the same result

d) can i view every orthographic elevation (including the other side views and the bottom view) or only those immediately visible.

apologies for potential stupid questions, all advice (and any other general tips for importing for rendering) greatly appreciated. thanks

a) yes and no.usaualy you want to work in somekind of pseudo realsize way. Where you asume each unit is 1 meter and forget you ever saw the uint in prefs... becasue its actualy confugured to be meter for mostly all other pactical meaning. If you use feet then by all means asume i unit is 1foot.

Whatever you do dont tell maya you defined a magic unit or youll curse the day you need dynamics.

dxf come in the scale you drew them. If you want to wor at this hude scale be sure to change your near far clipping scales as well as your locator scales

Yes it easy to sacle down group and scale down.

c) sure why not but its realy hard to tell as dimension is in thjis apsect a bot undefined. But yes you can meake a tool that measures for example bounding box sacel and sales based on thet or then by change in some ine dimesion protactors scale or whatever. No such tool by default. Not taht one ever actualy need sone realy.

d) yes you can! theres jsut only 4 cameras by default.

PS you should realy realy upgrade to maya 7.

[nice one cheers. not too sure exactly what you meant concerning the dimensionning question but shall head back and have another look around. did you mean that i have to script a tool to do this (in which case i might give it a while before playing around with the guts)? or some other technique?

thanks for reply (is maya 7 really worth the jump?)

definetly (even just maya 6 and 6.5 is definetly worth upgrade), besides that all maya wersions are worrth the money. HOWEVER, you dont wwant to purchase maya alone what any sane peoson does is gets maya and the platinum membership, then the upgrades come rolling.
