Your budget is at a no-mans-land, in a way 
Solidwork and Pro E really can make use of Quadro / FirePro GPU, but models that spec with them are out of your budget.

Dell
Precision M4800

HP
ZBook 15, i7-4700MQ + Nvidia Quadro K1100M + (1920x1080; anti glare)@RM6399, 4GB, 750GB(7200rpm), W8

Illegear RS-15, i7-4700MQ + AMD 8970M + (1920x1080)@RM5799[3.1kg][Onkyo, SoundBlaster X-FI MB3], 8GB, 500GB(7200rpm), Multi-Color Programmable Backlit Keyboard, FreeDOS, [CPU Options: i5-4200M - i7-4930MX] [GPU Options: AMD 8970M, Nvidia GTX765M, Nvidia GTX770M, Nvidia GTX780M, Nvidia Quadro K1000M, Nvidia Quadro K3000M

So you are basically left with consumer class machine with consumer class GeForce GPU (AutoCAD is good since latest version has migrated to DirectX).

Asus
N550JV-CN077H, i7-4700HQ + Nvidia GT750M + (1920x1080; IPS matte)@RM3799[2.7kg], 4GB, 1TB, W8, backlit keyboard

HP

Illegear RE-15, i5-4200M + Nvidia GTX765M + (1920x1080)@RM3499[2.6kg][Onkyo, SoundBlaster Cinema], 4GB, 500GB(7200rpm), FreeDOS, [CPU Options: i5-4200M - i7-4900MQ]

Prices are RSP, negotiable.

M4800 is expensive, > RM6k We don't have detail spec and price anymore, you have to ask Dell distributors for quotation.

Precision, Thinkpad W, Elitebook are all good stuff.
Those are older models, you really need to do leg work to find stock (and make sure they are brand new sealed unit, not display / refurbished unit.)

EliteBook 8570w, i7-3520M + Nvidia Quadro K1000M + (1920x1080) + Bluray@RM6299, 4GB, 750GB(7200rpm), W7P/W8
EliteBook 8470w, i7-3520M + AMD FirePro M2000 + (1600x900)@RM5099, 4GB, 500GB(7200rpm), W7P, anti-glare, 3 years
Precison M4700, i7-3720M + Nvidia Quadro K1000M@RM5800, 4GB, 750GB(7200rpm), W7P [Screen Upgrade: FHD, FHD IPS RGB] [CPU Upgrade: up to i7-3920XM] [GPU Upgrade: Quadro K2000M] [RAM up to 32GB]

Yes, mobile workstation is expensive. If you don't need mobility, stick with desktop, a lot cheaper

If you can still find EliteBook 8470W brand new unit, by all means go for it
SSD will improve responsiveness a lot whenever laptop need to save/read file, do window swap file, boot up, ... you can make do with HDD 1st, and upgrade later on if you want. 256GB is ~ RM600. SSD price is dropping fast every year, so may be 2 years later, for RM600 you can get SSD of much larger capacity.
"no-man's-land" - neither here nor there. Your budget is a bit short for a great mobile workstation, but too much for a consumer class machine
